About OLEDs

OLEDs (organic light-emitting diodes) are solid-state devices composed of multiple thin layers of organic materials often only a few nanometers thick that emit diffuse light when electricity is applied to them. Because they are an area light source, OLEDs are a key part of fulfilling the dream of the rapidly growing flat panel display market: paper-thin, highly-efficient displays with brilliant colors and excellent design flexibility. OLEDs may also lead to innovative decorative lighting applications and personalized environments. www.novaled.com/oleds/

[Press Release] OLED production capacity will increase to double in 2023.

UBI Research has published [2019 OLED Equipment Report] that forecasts the OLED equipment market. According to the report, the total substrate area of display companies in 2019 will be 34.9 million square meters, which will be 68.5 million square meters in 2023 and double after four years.

OLED substrate area growth is attributable to investments made by OLED lines for TVs driven by Samsung Display and LG Display. Currently, OLED manufacturing lines for TVs are 8G lines optimized for 55-inch panel production. However, the demand for premium TVs is shifting from 55-inch OLED TVs to 65-inch TVs. By 2021, the 65-inch OLED TV market will account for more than 40%. In response to these market conditions, LG Display is preparing to invest 10.5G lines in the most efficient production of 65-inch panels. In 2023, the substrate area of a large OLED line is expected to occupy 42% of the total substrate area.

<OLED production capacity by generation>

The substrate area of the 6G line is expected to grow to 13 million square meters this year and to 19.3 million square meters in 2023. Most of this is due to investment by Chinese panel makers. In China, the smartphone market accounts for about 40% of the global market, so Chinese smartphone makers have a very high market share based on the domestic market. Huawei has recently become the world’s second-largest shipper based on its domestic market. Chinese panel makers are boldly adding a 6G flexible OLED line to Chinese smartphone makers, with the Chinese government’s huge support.

<OLED production capacity by country>

In 2019, Korea’s OLED production capacity (substrate area) will total 27.9 million square meters, accounting for 80% of its total production capacity and expanding to 54.8 million square meters by 2023. The market share will remain at 80% and lead the OLED industry.

Chinese panel makers are expected to stay at around 20% as they are investing only in OLED production lines for mobile device.

The OLED manufacturing equipment market (excluding logistics equipment) is estimated at $ 28.4 billion for four years from 2019 to 2022 due to investment by Korean and Chinese panel makers. Among them, the sixth-generation equipment market is expected to account for 61% of the total equipment market, at $ 17.2 billion.

[SID2019] What material is better for cover windows of foldable OLED? colorless PI or UTG?

Since Royole introduced ‘FlexPai’, a foldable OLED phone, Samsung Electronics and Huawei have also launched Foldable OLED phones, attracting great interest from the industry and the public.

The biggest change of the foldable OLED phone currently being commercialized or under preparation is that the cover window of the glass material used in the existing flexible OLED has been changed to colorless PI material.

Colorless PI is thinner than conventional cover window glass, which is advantageous in reducing the radius of curvature and has the advantage of not breaking. UTG (ultra-thin glass), which has good surface touch-feel and scratch-resistant glass as thin as possible, is also attracting attention as a cover window material for foldable OLEDs.

At the SID Display Week exhibition in San Jose, KOLON exhibited colorless PI with hard coating. KOLON, which has been ready for mass production of colorless PI since 2018, is currently supplying colorless PI for foldable OLED cover windows to AUO, BOE, LG Display, and Royole.

Hard coating company DNP and TOYOCHEM also exhibited colorless PI with hard coating. DNP’s company official said that the film is under development and its main business area is hard coating, and TOYOCHEM’s company official said that it supplied hard coating samples to KOLON and SKC.

Meanwhile, SCHOTT, a UTG development company, also attracted the attention of the audience by displaying UTG for foldable OLED cover windows. An official of SCHOTT said that the UTG currently being developed is a cover window product for out-folding, not in-folding, and that the thickness is currently in development from 0.7 mm to 2.5 mm in accordance with customer requirements.

As the smartphone set makers are expected to release foldable OLED phones in the near future, competition for related materials is also expected to be intense. Whether the Colorless PI will continue to dominate or whether UTG will be able to exercise its influence is highlighted.

2019 Chinese OLED panel maker equipment order status

As Korean OLED panel makers do not have a lot of investment, the OLED equipment industry is in a low-demand season. When Chinese OLED panel makers confirm the order status of equipment orders in 2019, orders are being made centering on equipment and module line equipment required for new technologies rather than new lines.

In China panel makers BOE and CSOT, some equipment was ordered in March of this year for the development of flexible on-cell touch technology, and Korean equipment makers seem to have received orders from Wonik IPS and Iruja. In addition, since last month, the BOE Chengdu line has begun full-scale mass production and ordering of modular products along with foldable product preparation. Korean equipment makers will also receive equipment orders from BOE and proceed with production.

Starting this month, Visionox Hebei Line, which is set to start full-fledged investment this year, has begun placing orders for long-term delivery equipment and automation equipment. In addition, Wuhan Tianma is making some complementary investments in flexible process equipment, and EDO, Royole, and Truly are expected to invest in the future depending on market conditions.

UBI Research AMOLED process equipment industry report, which is scheduled to be published in May 2019, will be covered in detail in investment situation and equipment supply chain in China panel makers.

[BOE Chengdu Module Line Order Status]

[Press Release] AMOLED components and materials market grew to $ 24.15 billion in 2023

Although Samsung Electronics and Apple’s OLED smartphone market are stalled, Chinese smartphone makers are gradually increasing their use of OLEDs based on the huge smartphone market in China. As a result, BOE and Chinese panel makers have aggressively established a Gen6n flexible OLED plant, which is driving the OLED industry.

As a result of UBI Research’s panel makers’ operation rate analysis due to OLED plant expansion and supply and demand, the market for various component materials (excluding light emitting materials) that make up OLEDs is expected to reach $13.9 billion in 2019 and expand to $ 24.15 billion in 2023.

Recently, as the production of foldable OLED has started, various kinds of films that are not applied to LCD are emerging as core materials.

In the [2019 OLED Components and Materials Report] published by UBI Research, we examined the foldable OLED structure of Samsung Display, LG Display, and BOE, and analyzed the thickness and characteristics of the films that make up the module.

In the OLED components and materials market, components for TV OLEDs will grow rapidly to reach $ 19.1 billion in 2023 and lead the OLED industry.

▶ LGD’s performance is in the doldrums. This year, it will compete with high-value OLEDs. (ZDNet Korea)

(Full text of article: http://www.zdnet.co.kr/view/?no=20190424130827)

While LG Display is recording poor performance in first quarter of this year, it is going to strengthen its competitive edge in OLED display, which is its main business. Because it is expected that Chinese LCD will continue to make inroads into supplies this year, Samsung Display is planning to bring about results through high-value OLEDs that are highly profitable.

“It seems that large OLED business will take up more than 30% of TV business in 2016 through changes in customer and high-end position.” said Seo Dong-hee, chief financial officer of LG Display, during a conference call on the first quarter of 2019.

“Although some fixed expenses are also expected in second half of this year due to preparation of (Guangzhou OLED fab) production infrastructure as planned, we will increase profit contribution starting from 2020.” said a representative for LG Display.

■ It is difficult to rebound in second quarter performance…compete with high-value OLED in second half.

LG Display also expects that its second-quarter earnings will continue to worsen market conditions due to oversupply of LCDs and lack of IT products. Consensus of second quarter’s performance that F& Guide is estimating is $5.58 trillion (5.8181 trillion KRW) in sales and $16 billion (16 billion KRW) in operating loss.

However, it is expecting that it will produce results starting from second half of this year due to operation of OLED production lines that are located in Guangzhou, China, and release effects of transparent and automatic OLEDs.

“We believe that Guangzhou fab will operate successfully during first half of this year. “We are also preparing to apply MMG (Multi Model Glass, which is a method that is produced by combining 55-inch and 65-inch panels) to Guangzhou and Paju fab.” said a representative for LG Display.

Furthermore, transparent OLED products will be released in second half of this year and will expand additional demands. “We are currently working with variety of customers in commercial business.” said a representative for OTO, “Auto is already making more than 1 trillion won in sales through LCD. During this year, you will be able to see vehicles with plastic OLEDs. Although it is difficult to mention exact numbers, South Korea has received a large number of orders for displays for vehicles that employ POLEDs. We believe that orders will also gain considerable momentum when cars with POLED are successfully released this year,” he stressed.

 

▶ FineTec Receives Intent for Purchase of OLED Bonding Equipment from Chinese Firms(NEWSPIM)

(Full text of article: http://www.newspim.com/news/view/20190424000218)

While demands for OLED panels are increasing rapidly due to the resumption of investments in Chinese OLEDs this year, FineTec is trying to expand its supply of bonding equipment to Chinese display-specialized companies.

FineTec made an announcement on the 24th that it recently received orders from Chinese display company BOE for OLED composite bonding equipment and received LOI (Lent of Purchase of OLED bonding equipment) from CSOT.

FineTec is planning to supply CSOT with equipment dedicated to chips on plastic and COP-COF (chip on film) and other composite equipment that can be produced simultaneously. It is predicted that it will sign a contract with CSOT to supply bonding equipment after discussing detailed timing of supply.

In addition, FineTec, which is currently seeking to diversify its suppliers to China, is planning to strengthen its competitive edge in operation such as OLED composite bonding equipment for CSOT starting with this contract.

“Chinese OLED panel manufacturers are increasing their market share thanks to government support and Chinese Smartphone manufacturers’ promotion.” said a representative for this company. “FineTec is planning to focus on improving performance by securing orders from Chinese suppliers as China is actively seeking to increase its market share in OLED.”

It is also expected that FinTec’s combined bonding equipment will expand its competitive edge in markets in China. Although FinTec had about 10% of orders for bonding equipment that was placed in China three years ago, percentage of orders from Chinese display companies such as BOE and Visionox increased to 26% last year due to increased demands for composite equipment.

“We are currently converting variety of display panels from facilities that are targeted at specific types of panels from China and around the world into multi-functional equipment that can be produced at the same time.” said a representative for Samsung Electronics.

▶ ” LCD TV panel price rebound…accelerates large OLED conversion” (The Korea Economic Daily)

(Full text of articles: https://www.hankyung.com/finance/article/2019042322206)

“The price of LCD TV panels increased +0.7% in second half of April compared to first half.” said KB Securities on 23rd.

“The price of LCD TV panels in the second half of April, which was announced by Witzview, has increased +0.7 percent compared to the first half,” said Dong-won Kim researcher. “The prices of 32-inch and 55-inch LCD panels increased +1.3% compared to the first half of April, and prices of 65-inch and 75-inch panels recorded 0.5% and 1.1% respectively, showing good trend of prices.” said a slight decrease in prices of PC panels compared to the previous quarter.

While positive trend of LCD prices is continuing in second quarter, it is predicted that businesses can convert large OLED panels faster. “If Samsung Display’s QD-OLED conversion investment for 8th generation LCD lines starts in earnest in the second quarter, price of 32-inch TV panels will continue to rebound slightly due to psychological impact on reduction of supply.” said Kim. “For 65-inch, 75-inch TV panel prices, production of Chinese panel manufacturers will expand, operation of 8th generation LCD lines of Samsung Display will slow down.”

The Chinese companies’ volume offensive raised concerns that the OLED industry, following liquid crystal displays, could face oversupply problems. Analysts say that while South Korean display manufacturers’ performance in the first quarter has deteriorated due to a sharp drop in prices of LCD panels, even OLEDs, which are seen as new growth engines, could be on the verge of oversupply in the near future.

According to a recent report released by Hana Financial Management Research Institute on Monday, the production capacity of OLED plants currently being built by Chinese companies such as BOE, CSOT and TCL is twice that of South Korea.

 

▶ Retirement of OLED business for general lighting… Accelerate selection and focus of ‘New LG’ (The Korea Economic Daily)

(Full text of articles: https://www.hankyung.com/economy/article/2019042211521)

LG Group is speeding up efforts to reorganize its business portfolio for future growth. LG Display’s decision to withdraw from its organic light-emitting diode (OLED) business for general lighting is part of its objection. The “choice and focus” strategy has become a keyword that penetrates LG Group Chairman Kwang-mo Koo “New LG,” who headed the group last year.

According to LG Group and others on the 22nd, LG Display has given up its OLED business for lighting that it has been pushing as a new growth engine. It has been about a year and six months since it started mass-producing products from new OLED production lines.

It is heard that LG Display has decided to withdraw from markets by gradually reducing mass production of OLEDs for lighting that are produced at 5th generation OLED lines (P5) in Gumi, North Gyeongsang Province. Instead, it has decided to focus on OLED markets for vehicles that have huge growth potential and can produce synergy with the group’s automotive electric field (electric and electronic devices) business. LG’s acquisition of ZKW, which is a global automotive headlamp manufacturer, also affected LG’s ability to provide lighting for vehicles.

LG Display entered the general lighting market by introducing a new brand called ‘Luplex’ at the end of 2017. However, it is rumored that it has decided to give up its business after losing out on price competition from current LED (light emitting diode) lighting companies.

▶ OLED is also worried about oversupply…” China factory size, twice that of Korea.” (YONHAP NEWS)

(Full text of articles: https://www.yna.co.kr/view/AKR20190419148900003?input=1195m)

Following LCD panels, there are predictions that oversupply can become a reality for OLED panels.

Concerns are growing as South Korean companies plan to grow OLEDs into new “cash cow” instead of LCDs that China has taken the lead.

According to a recent report released by Hana Financial Management Research Institute on 21th, the number of OLED panel factories currently under construction in China is 419,000 sheets per month, about twice the amount of 225,000 sheets per month, which is the size of South Korea’s expansion.

According to the report, China’s BOE, which ranks first in LCD panel market, is going to increase its size to 144,000 panels. In addition, Chinese panel manufacturers such as CSOT, Visionox, and TCL are also scrambling to expand their facilities on a large scale.

Among South Korean companies, LG Display is set to operate its 90,000-unit monthly plant in Guangzhou, China, and it is expected that there will be a total of 45,000 panels per month in Paju.

Industries predict that size of OLED plant that will be built by Samsung Display in Tangjeong, South Chungcheong Province, will reach 90,000 sheets per month.

“As speed of expansion of OLEDs in South Korea and China is much faster than rate of increase in demands, there is a high possibility that oversupply will worsen.” said Joo-wan Lee, a researcher.

 

▶ The screen shield that caused controversy over faulty Galaxy folds…Why do I need it? (Yonhap news)

(Full text of articles: https://www.yna.co.kr/view/AKR20190421010700017?input=1195m)

Samsung Electronics’ first foldable Smartphone was embroiled in controversy over its screen defects even before it was released. Samsung Electronics explains that this happened because early users removed “screen protection film,” which can be misunderstood as screen protection film.

<Samsung Electronics [Samsung Electronics Co., Ltd.]>

According to industries on the 21st, current Smartphones are going to protect displays by attaching cover windows with reinforced glass material on top of OLED display panels.

OLED panels themselves are very thin like vinyl and are weak against external shocks. Plastic OLED (Plastic OLED) that is used for foldable Smartphones is more vulnerable to scratch. However, it can’t put glass, which is a material that doesn’t fold, so it is finished by applying film of plastic material.

“Although screen protection films that we already know are additional products that prevent scratching, protective films that are used for flexible displays are very important for displays.” said Professor Hak-seon Kim of UNIST, who is a former vice president of Samsung Display. Ok-hyun Jeong, an electronic engineering professor at Sogang University, also said, “The fact that we took out a protective film from PLED is tantamount to ripping off the display parts themselves.”

OLEDs emit light as organic materials, and due to their characteristics, they are very susceptible to oxygen and moisture components. When a thin panel itself is subjected to strong pressure during a screen’s opening, it can cause the screen itself to become indigestion due to moisture in an empty space.

Plastic has a weaker hardness than glass, making it easier to scratch the surface.

In addition to screen glitches, the media that received Galaxy Folders for review such as Bloomberg and Derverge points out that the protective film is easily dented or scratched. One reviewer said, “I tapped the screen with my fingernails, but there are still permanent marks.”

Some point out that there is a gap between the protective film and the display, which makes it easier for dust and others to get rid of it. One reviewer suggested a photo showing the gap between the screen’s protective screen and bezel, suggesting that it could be misleading.

Due to this reason, Samsung Electronics explained that its screen shield is for ‘replacement’. Since there is a higher chance of damage such as scratch than conventional glass, they were made so that they could be replaced at that time. However, users should not replace them directly and go through a service center.

Experts point out that such precautions should be sufficiently notified to consumers before the launch, and that early users also need to follow basic precautions as they use first-generation products.

Jeong said, “Samsung Electronics seems to have lacked notice of screen protection. “We need to strengthen advance notice when it is officially released.” said a person who dropped it from the company, which is about 100 grams more than normal Smartphones, risks further damage when it is dropped from the same location. This part also requires the user to pay attention,” he pointed out.

“Since the film itself is a plastic material, even if it is attached with protective film, it can be pierced and torn if exposed to sharp needles, unlike glass,” Professor Kim said. “In fact, these precautions should be properly introduced when selling it.”

 

▶ SK is investing in OLED business? (etoday)

(Full text of articles: http://www.etoday.co.kr/news/section/newsview.php?idxno=1747027)

SK Corp. is considering investing into OLED material business. As OLED markets are rapidly growing, industries that are made of OLED materials are also increasing.

According to mid- and long-term management plan data that SK Corp. held a corporate briefing for analysts of securities companies on Wednesday, SK Corp. is also reportedly considering investing in OLED materials to expand its material business.

SK Corp. has set a mid- and long-term strategy for its material business to expand its high-growth area by utilizing its current material platform.

For OLED materials, LG Display is planning to develop its own technologies by linking current SK Trichem’s technologies such as precursors and others while also considering investing in them.

Industries predict that SK Corp. will be able to expand its business through investments as it is an investment-type holding company.

For battery materials, which are planning to enter markets with high-entry barrier materials through partner companies’ cooperation and investment in technology holding companies, it has quickly entered the market by investing 270 billion won into shares of related companies.

SK Corp. previously acquired the stake in Watson, China’s No. 1 company that manufactures the second-order essential part of the battery, in November last year.

A reason why SK is showing interest in OLED markets is because OLED markets are growing rapidly.

According to a market research company called Ubi Research, size of OLED display market was estimated to be $28.31 billion (31.9568 trillion KRW) last year, which is a 7.1% increase year-on-year and is expected to grow to $32.3 billion (36.457 trillion KRW) this year.

It is expected to grow to $59.5 billion by 2023.

As a result, many other companies are working on OLED materials. Earlier this month, LG Chem stepped up its related business by acquiring material technology for “Solid Organic Light Emitting Diodes,” a key platform for next-generation displays, from DuPont in the U.S.

Doosan also established a new company through division of its business sector to strengthen its material businesses such as OLED.

“We have no specific plan to invest in OLED materials yet.” said a representative for SK Corp.

OLED emitting materials market to grow to $ 1.71 billion in 2019

OLED light emitting materials market is gradually increasing as Chinese companies enter OLED panel market led by Samsung Display and LG Display.

The 2019 OLED emitting material report, published by UBI Research, predicts that the emitting material market in 2019 will reach $ 1.17 billion. 2021 and 2023 are expected to grow to $ 1.87 billion and $ 2.0 billion, respectively.

The size of light emitting materials consumed by Korean companies will account for 70.2% in 2019 ($ 0.82 billion), and its share will increase to 75.6% in 2023.

Korea’s emitting material market is growing because the consumption of OLED materials for TVs is soaring. In 2019, 21.1% of light emitting materials for TVs are expected to increase to 49.7% in 2023.

Also, TCL announced the prototype device uses the company’s proprietary “DragonHinge” mechanism to fold and unfold the screen, it has 7.2-inch screen.

According to TCL, this device will build a production version that is slated for release by 2021.

Lastly, LG showed off V50 which is similar to a folding phone, it does have an optional case with a whole second screen on it. With two near-identical phone displays next to each other, the functional split-screen allows multitasking and gaming easily.

What is the cost of OLED materials for the Galaxy F?

What will be the price of foldable phone Galaxy F, which is expected to be on the market this year, is a concern for people around the world. Samsung Display is the only company that can mass-produce Foldable OLEDs with in-folding type used by Galaxy F.

Galaxy F with 7.29-inch OLED is a digital convergence product that can simultaneously target the smartphone and tablet PC market. The initial sale price will be around $ 2,000, and the estimated sales volume is about 1 million units this year.

The OLED industry is interested in how much the Galaxy F’s foldable OLED panels (including modules) will cost.

According to UBI Research’s material cost analysis data, Samsung Display’s foldable OLED material cost is 2.04 times higher than the Galaxy S10 5.8 inch. This is because the display area has increased, and the yield has been reduced.

Galaxy F, Galaxy S10, and iPhone XS’s flexible OLED material cost analysis shows that the module cost of iPhone XS is the highest at 95.2%, Galaxy S10 at 92.2% and Galaxy F at 89.3%.

Quarterly OLED Market Report for TVs

[Press Release] AMOLED sales to reach USD 32.2 billion in 2019, up 13.8% from 2018

UBI Research (CEO, Yi, Choonghoon) published the annual OLED report in 2019.

According to the report, the OLED market is expected to reach $ 32.2 billion in 2019 and 13.8% market growth. The market growth is due to the launch of a variety of applications in 2019. Foldable OLED will accelerate the growth of the flexible OLED market as a convergence product that fuses smartphones and tablet PCs, and 8K OLEDs and rollable OLEDs to be launched from 2H 2019 will further solidly support the premium OLED TV market. In addition, an increase in flexible OLED shipments due to improved yields by Chinese panel makers will support growth in the Chinese OLED market.

AMOLED revenue in the fourth quarter of 2018 was $ 7.9 billion, down 3.7% from $ 8.2 billion in the third quarter and down 10.4% from $ 8.8 billion in the fourth quarter of 2017. The quarterly OLED market was highly volatile due to sales fluctuations at Samsung Display.

Revenue in 2018 was $ 28.3 billion, up 7.1% from $ 26.4 billion in 2017. The growth slowed suddenly compared to growth of 58.7% in 2017. The sluggish growth is attributable to the sluggish OLED smartphone market, which drove the OLED market up until now. The OLED market for smartphones, which was worth $ 24.2 billion in 2017, was only $ 24.5 billion in 2018.

Flexible OLED panels are not being adopted in mid-end smartphones due to the high cost of manufacturing flexible OLED panels for smartphones. As a result, the oversupply will continue due to lack of demand compared to the 6G flexible OLED investment. In the fourth quarter of 2018, there was an oversupply of 31%. In the first quarter of 2019, oversupply will increase to 39% by overlapping seasonal demand decline.

LG Display “OLED TV will account for more than 20% in total TV sales revenue.”

LG Display OLED TV maintained sales revenue, it through conference call, stated it recorded annual sales revenue of 24.3 trillion won and 92.9 billion won operating profit in year of 2018.

LG Display despite of heightened global competition and downward panel price made an operating profit thanks to OLED TV, super large size TV and high resolution products.

Especially large size OLED TV maintained stable productivity and enlarged consumer bracket which enabled 2.9 million shipment on a yearly basis. It recorded gross profit within 5 years of product introduction which resulted in more than 20% in total sales revenue.

4th quarter 2018 revenue of LG display marked 6.95 trillion won TV panels accounts for 36%, mobile panels 28%, notebook and tablet panels 22% and 14% for monitor panels.

Operating profit recorded 279 billion won, 528% increase compared to the same quarter last year, 99% hike compared to last quarter thanks to high priced IT products, new introductions of small and medium size products and high added value products. LG Display aims to focus on OLED business reconstruction Seo Donghee CFO of the company said, “the ratio of OLED revenue was almost nothing 5years ago, now it is 30% this year and we estimate it is going to reach 50% of the total business.”

He also said “we will put in all assets to create new values focusing on OLED business.”

He replied to the question of large size QD-OLED of competitor, it will strengthen ecosystem and overall OLED industry. To the question of 8K and over 70inch large size OLED mass production, he replied that 8K technology is already secured as exhibited at CES2019 and said that large size OLED mass production will utilize the existing know-how of LCD production. In 2019, LG Display’s OLED demand outlook question suggests that demand for more than 14% of all flexible OLED smartphones is expected.

Regarding the large-area OLED and p OLED capacity in 2019, LGD said that the large-area OLED capacity will be completed at 70K per month in Paju and 60K in Q3 in Guangzhou, China and the pOLED capacity is expected to add 30K to the domestic 45K in 2020.

He announced that capex is estimated 8trillion won in 2019 and 4trillion won in 2020, a half of this year. 60% will be for large size OLED and 40% for pOLED. And he said pOLED mass production is currently concentrated on smart phone and cars. He expects good news from car pOLED by end of this year. He also targets over 3.8 million units large size OLED production this year.

55 inch and 65 inch OLED TV prices proximity to premium LCD TV

Recently, Sony’s 65 inch OLED TV, XBR65A1E, is price at US$ 300 more than Samsung’s QN65Q7 on the Best Buy basis. Prices of LED TV and LCD TV are becoming increasingly competitiveness in the premium TV market.

As of January 16, Best Buy compares the price of OLED TVs between LG’s C8 series, Sony’s A1E series and Samsung’s Q7F series.

<55 inch premium TV price comparison>

LG’s OLED 55C8 prices dropped 47% from March 2018 to US$ 1,700, which is only US$ 200 higher than Samsung’s QN55Q7.

<65 inch premium TV price comparison>

In the 65 inch TV market, LG’s OLED65C8 price dropped 30% from March 2018 to US$ 2,700, while Sony fell 40% to US$ 2,500, which is higher than Samsung’s QN65Q7 by US$ 500 and US$ 300. The prices gap has been greatly reduced.

In the premium TV market, OLED TVs are rapidly catching up with LCD TV prices because LG Display’s OLED production yield stabilization is the biggest factor.

LG Display is currently constructing Gen8 OLED lines in Guangzhou and Gen10.5 lines in Paju. As a result, the production of large size OLED will increase further, and the OLED TV market will become more prominent in the premium TV market.

CES2019, the biggest issue of TV is LG Electronics OLED TV R

Reporter : Daejeong Yoon

The CES, held in early January of each year, is the most important event to understand all of the consumer electronics trends of the year. This year, TV makers from all over the world exhibited a variety of products to attract spectators to the event.

When OLED TV occupied more than 50% of the premium TV market with more than $ 2,000, the LCD TV industry sought to prevent the OLED TV market from expanding by exhibiting 8K LCD TVs to CES. However, the attention and admiration of the spectators were poured into OLED TV R.

The 8K TV market began to open slightly from last year, in preparation for the 8K broadcast starting from the Tokyo Olympics in 2020. LCD TV companies displayed 8K LCD TVs of various sizes to preoccupy the market with the keyword of 8K. LCD TV, however, has not been recognized by viewers as a new TV product since Sharp has already exhibited steadily.

Another reason is OLED TV R displayed by LG Electronics. In the main body with built-in speaker, OLED TV rises up and goes down again. A lot of people came to see OLED TV R to shoot.

 <LG Electronics, OLED TV R>

Last year, micro LED TVs became more prominent. In addition to Samsung Electronics, Sony, TCL and Hisense exhibited micro LED TVs this year. It seems that the gap of micro LED TV technology between Korean companies and Chinese companies is only about one year. In the micro LED TV market based on assembly technology that does not require special manufacturing technology, China, which is the world’s best LED industry and infrastructure, is expected to dominate the market soon.

However, as LG Display has a unique OLED TV manufacturing technology, which has a very complicated panel structure and manufacturing process, the technological gap between Korea and China is expected to be more than five years difference. In this situation, OLED TV R, released by LG Electronics, once again realizes that Korea’s OLED technology is the best in the world.

On the other hand, TV companies’ display of OLED TVs, except for LG Electronics, has stagnated. These companies are not yet receiving 8K OLED panels and rollable OLED panels from LG Display. Even Sony does not have any special features, only OLED TVs that are well known so far.

As a result, the CES TV show was notable only for LG Electronics.

It is judged that LCD TV using mini LED that TCL has released can compete with OLED TV in this exhibition. The contrast ratio is displayed as 1,000,000: 1 similar to OLED TV. Black is a very good product that has a vibrant color and contrast ratio similar to OLED TV. However, a holo-effect was found around the bright screen displayed on the black desktop. It is a phenomenon that the surroundings appear to spread brightly. As it is invisible to non-specialists, it is competitive in price and is a product that can compete well with OLED TVs.

LG Display Vice Chairman Han Sang-Bum, “50% of sales of OLED and upbringing business in 2020”

Growing into the mainstream of OLED growth by expanding large OLED, differentiated products and supply

■ Small and Medium-sized POLED, strengthening fundamental business capacity and preparing future products such as Foldable

■ Develop commercial and automotive products, new technologies / new markets and develop into first-class business

LG Display is one of the world’s largest electronics exhibitors, and will hold a press conference at the Las Vegas Convention Center (LVCC) in Las Vegas on June 7, the day before the opening of the Consumer Electronics Show (CES) with Han vice chairman, executive vice president Kang In-Byoung, Strategy and Marketing Group Director Song Young-kwon, and other executives.

At the meeting, Han Sang-bum said, “Although there were many difficulties due to excessive supply and enormous investment due to intensified global competition last year, large-sized OLED business turned to surplus and stable profit was generated mainly in high value-added products. “This year, LG Display will focus on OLED investments, accelerating OLED growth, and focus on commercial and automotive businesses. By 2020, LGD will account for more than 50% of total OLED and growth businesses. “He said.

To this end, LG Display plans to expand its large-size OLED market, strengthen its fundamental business capabilities in small- and mid-sized P-OLED (plastic OLED) businesses, and develop new markets with differentiated commercial and automotive products.

■ Large OLED, differentiated products and supply expansion

Since LG Display first supplied OLED TV panels in 2013, LG Display has continued to develop its technology. And last year, it sold nearly 3 million units and developed into a strong player in the premium TV market. This year, the company plans to expand its TV product lineup from the existing 4K resolution to 8K, and to further enhance its competitiveness by further enhancing performance such as luminance and response time. In addition, the company will expand its market by expanding differentiated products such as wall paper, CSO (Crystal Sound OLED), rollable and transparent display. LG Display will complete the G8.5 OLED panel factory in Guangzhou, China in the first half of this year, and mass-produce OLED from the third quarter. Through this, the company plans to expand its sales volume from 2.9 million units in 2018 to 4 million units this year, and to achieve more than 10 million units in 2021.

In addition, LGD will expand sales areas for existing customers, strengthen collaboration with strategic customers, and increase sales of premium products such as ultra-large size panel.

■ Small and mid-sized P-OLED, strengthening fundamental business capacity and preparing future products.

LG Display is targeting the small- and mid-sized OLED market through P-OLED.

This year, it is a great challenge to develop core technologies and products for strategic customers in a timely to raise market share of small- and medium-sized panel.

In addition, LGD plans to increase the production capacity of the Gen 6 Gumi factory, which has a capacity of 15,000 sheets per month, and to expand the P-OLED production capacity by early stabilizing the Gen 6 factory in Paju.

In addition, LGD plans to steadily prepare related technologies and infrastructure so that future products such as Foldable can be released on time.

■ Commercial and automotive displays, Fostering first-class business

LG Display nurtures the rapidly growing commercial and automotive businesses to first-class business.

In the commercial market, LGD plans to pursue differentiated products such as 98 and 86 inches, ultra-slim products such as in-touch, bezel of 0.44 mm, transparent and gaming.

For automobiles, LTPS-based high-resolution LCDs and P-OLEDs are expected to focus on 8-inch and larger screens and high-resolution products. In addition, LGD will prepare its production infrastructure to expand its business in a timely manner and further strengthen its cost competitiveness, thereby achieving the first place in the fast growing auto market.

This year LGD plans to complete investment in preparation for the future, which began in 2017. LGD Han Sang-Bum, vice chairman of LG Display, said, “LG Display will be able to lead the global display market once again with OLED.

What is the biggest issue in the display industry in 2019?

In 2019, 8K OLED TVs and foldable smartphone will be on sale, bring new vitality to the OLED industry. OLED makers are leading the market with high-value-added products in order to maintain the display industry, which is collapsing due to low-cost LCDs pouring from the Gen10.5 line of Chinese panel makers.

Samsung Display is developing QD-OLED panels for the rapidly growing OLED TV market, and LG Display is spurring the development of foldable OLEDs for high-end smartphone market.

TCL and JOLED, which are relatively slower than Samsung and LG, are pioneering the soluble OLED market in response to the large-size OLED TV market.

The 2019 OLED KOREA will be held at the Novotel Hotel in Seoul from March 6 to 7 to enable you to understand the evolving OLED industry and technological development. The 2019 OLED KOREA, which includes Samsung and LG as well as the OLED industry, will provide insights into how and where the OLED industry will go in 2019.

[28TH FINETECH JAPAN] Denso, Automotive displays that are directly connected to safety are OLED

Reporter : Daejeong Yoon

At the 28th FINETECH JAPAN held in Makuhari Messe, Japan during December 5-7, 2018, Hiroyuki Hara, manager of Denso said that OLED will be used as future automotive displays due to their various advantages.

Hara refers to the large screen including the touch panel as the latest trend of automobile display, and now LCD is mainly used. However, OLED is expected to be used more and more in automobiles as the automotive electronics makers and drivers demand high-quality displays.

Saying that key elements in automotive displays are high contrast ratio, wide viewing angle, design autonomy, light weight, low reflection and reliability, Hara emphasized that the display that can satisfy all of these key elements is OLED. In addition, the factors related to image quality such as contrast ratio and viewing angle are directly related to safety for the driver. Thus, OLED is to be adopted more. Referring to the requirements of automotive OLED, he finally commented that improving reliability, such as lowering the luminance drop due to temperature changes and preventing damage to OLED due to high humidity, will be key to OLED for its entry into the automotive display market.

The automotive display is likely to lead the market for next-generation displays following mobile devices and TVs. Various OLED panel makers such as BOE and Visionox, as well as LG Display and Samsung Display, are showing automotive displays at domestic and international exhibitions. Denso also invested Japanese yen 30 billion in JOLED early 2018 to compete with Korean panel makers. Meanwhile, the market for OLED displays for automobiles led by Samsung Display and LG Display is expected to grow to US$ 540 million in 2023 according to UBI Research’s recently published “Automotive OLED Display Report”.

[28TH FINETECH JAPAN] JDI and JOLED, announced Strengthening Cooperation for Mid-sized OLED Market

At the 28th FINETECH JAPAN held in Tokyo, Japan from December 5 to 7, 2018, JDI and JOLED announced that they would intensify their cooperation in order to target the middle-sized OLED market.

JDI announced that it will actively promote JOLED’s solution process OLED to medium-sized OLED markets such as industrial display markets or automotive display markets through its own design know-how, production infrastructure, and sales channels,.

In particular, JDI announced that it will provide new value to next-generation automotive fields along with JOLED such as support for safety such as electronic mirrors and displays for A/B pillars, new interface functions, movie appreciation using 4-8K displays, and the displays that are harmonized with interior design such as curved surfaces and big screens.

JDI and JOLED also shared booths for exhibition. JOLED introduced 21.6-inch FHD OLED monitors for e-sports and medical applications. In addition, it introduced a number of medium-sized OLEDs such as 12.3-inch HD OLED for automobiles, 12.2-inch FHD flexible OLED, 27-inch 4K OLED for home interior, and 21.6-inch 4K flexible OLED with cylindrical form. It also showcased large OLEDs such as 54.6 inch 4K OLED.

On the other hand, JOLED announced in July, 2018 that it would open its Nomi office for mass production of solution process OLED. Based on 5.5 generation glass substrates, Nomi has production capacity of 20,000 glass substrates per month and plans to mass-produce in 2020.

[Press Release] Foldable OLED Market Grows Fast to US$ 24.6 Billion by 2023

Reporter & Analyst : Daejeong Yoon

5G communication technology introduced from next year can process higher image quality and large-capacity contents such as VR more rapidly, besides real-time streaming service. As the communication speed increases, the relevant contents, are expected to be released, which require high resolution and large screen with graphics detailed.

The current smart phone is getting bigger up to 6 inches, but it is not enough for 4K resolution of 5G communication age. Since 4K resolution is to be possible at 7-inch and larger displays, they might be the most suitable product for the 5G communication era. Foldable smart phones are digital convergence products that can function as smart phones and tablet PCs as the next generation mobile devices that use 7 inch or more displays but maximize portability.

Owing to foldable OLED, foldable smart phones are likely to be available. Several companies have rushed to produce various prototype foldable OLED displays at exhibitions and conferences. A few panel makers even pledged to mass-produce foldable OLED displays competitively. OLED display companies worldwide including Samsung Display have invested enormous development costs in order to preempt the next generation product market, and now foldable OLEDs are starting to appear.

Samsung Electronics, which is leading the OLED smart phone market, is planned to launch the in-folding type foldable phone for the first time in the world next year. Accordingly, Samsung Display has prepared 1.5R foldable OLED. For Samsung Electronics, which has suffered sluggish sales of the Galaxy S series, Foldable Phone is a super premium product that needs to be succeeded.

UBI Research (CEO: Yi, Choong-hoon), an OLED research institute, has published Foldable OLED Report. According to the report, the market for foldable OLED in 2019 is only US$ 480 million, but it is expected to grow to US $ 24.6 billion in 2023.

Yi said, “The rapid growth of the foldable OLED market is due to the fact that 7-inch and larger smartphones, which can support 4K resolution, become required products in the 5G communication era. Accordingly, the value of OLED panel makers will be determined by the success of foldable OLED production.”

However, foldable OLED is not a product that anyone can produce. Since foldable OLED has a more complex module structure than conventional flexible OLED, it is necessary to overcome the changes in various panel characteristics caused by folding. Especially in in-folding type foldable OLED, compensation circuit technology to overcome TFT resistance change and resilience required when folding and unfolding screen are typical technical difficulties. In order to realize this technology, the key challenges of reducing stress at the area of folding, selecting a proper substrate, determining the ideal stack structure, and optimizing the liftoff process, need to be overcome. Even when folding over 200,000 times, it is required to have reliability that there will be no abnormality on display image quality and surface.

“Foldable OLED Report” published by UBI Research analyzes the development trends of panel makers together with the development issues of major films that determine the reliability of foldable OLED.

JOLED, introduced many inkjet OLED technologies

This was the first time for JOLED to demonstrate its products and technologies at FINETECH Japan 2018.

JOLED, which received the inkjet OLED technology from Panasonic and is doing OLED panel business, has been selling medical monitors since early this year. Next year, Asus is also scheduled to sell inkjet OLED TVs made by JOLED.

Its exhibited products include medical OLED monitor, OLED monitor for games, automotive OLED and 3 kinds of OLED TVs.

 

JOLED’s Inkjet OLEDs have a peak intensity of 350 nit. In case of full white, it is 140 nits, but has sufficient brightness for monitor applications.

JOLED will build mass production lines next year to produce OLEDs for 20-inch monitors and TVs as a full-scale. It also plans to start OLED business for automobiles after 2020.

JOLED is the only company producing OLED panels manufactured by inkjet technology. JOLED is also promoting the license business by providing this technology to Chinese, Japanese and Taiwanese panel makers.

[28TH FINETECH JAPAN] Sharp, announced Future Strategy Combining IGZO and OLED

Mr. Atsushi Ban, Vice President of Sharp presented a future strategy that combines IGZO and OLED through a keynote session at the 28th FINETECH JAPAN, held in Makuhari Messe, Japan from December 5, 2018.

Ban emphasized “The proportion of OLED in the entire display market is expected to grow even higher, and the new value of OLED is no different than flexibility.”

He said, “Sharp is also planning a variety of applications using the thin, light-weight and flexible characteristics of OLED. From the third quarter of 2018, its Taki plant has produced 4.5G backplanes and the Sakai plant is under injecting glass for OLED and module processing for 4.5G 15K quantity.”

 

 

Ban also pointed out the possibility of expanding the OLED industry through flexible OLED, commenting that Sharp’s next goal is to develop foldable OLED that combines IGZO. Sharp has pioneered a new display technology, called IGZO, which has been known for its semiconductor properties for years, but Sharp has developed a crystalline form that maximizes its benefits for greater display performance, and IGZO improves the performance of display panels in three significant ways: lower power consumption, higher resolution and special benefits for touch-sensitive displays. Ban expected that it could create new value if IGZO is combined with medium to large sized foldable OLED or rollable OLED.

 

Finally, Ban introduced Sharp’s IGZO development roadmap and announced that it will develop much improved IGZO.

Fingerprint full-screen smart phones begin to compete

Reporter : Daejeong Yoon

<Vivo’s full screen smart phone with in-display fingerprint scanner, Android authority>

The competition for front fingerprint recognition of smart phones is expected to become hot.

In the smart phone with the existing home button, the front fingerprint sensor was installed on the home button. Fingerprint security enhances security, but recently, full screen Smartphone without home button has been released and fingerprint sensor has been moved to the back of Smartphone. This has caused disadvantages such as an uncomfortable hand shape when touching a finger to the fingerprint sensor and fingerprints on the camera lens.

In order to improve these points and to implement a complete full-screen Smartphone, the development of integrating full-screen fingerprint recognition with display is continuing.

The method of full-screen fingerprint recognition is largely examined by both optical and ultrasonic methods. The optics are inexpensive and easy to mass-produce, but the OLED substrate must be transparent because the sensor is to be located below the OLED panel. Therefore, it is applicable to rigid OLED using glass as a substrate, but it is difficult to apply to flexible OLED using colored PI as a substrate. The ultrasonic method is most stable in accuracy and durability, but it has a disadvantage of high manufacturing cost.

Currently, Chinese set makers have begun to launch smart phones with optical front fingerprint recognition. The Galaxy S10, which will be released next year by Samsung Electronics, is being watched for the adoption of ultrasonic full-screen fingerprint recognition. LG Display is also developing a display with front fingerprint recognition.

As such, the sales for full-screen smart phones with front fingerprint recognition are expected to be started in earnest. Competition in the smartphone market is expected to become more intense in the second half.

OLEDWorks, released LumiCurve Wave, a flexible OLED lighting.

OLEDWorks recently announced the release of ‘Wave’, the first commercially available OLED (organic light-emitting diode) lighting platform on flexible glass.

Because plastic film is used for the cover window of foldable phone, the display of out folding foldable phone is very likely to be damaged due to the external environment.

In fact, Samsung Display already developed a QHD resolution outfolding foldable OLED with a bending radius of 5 mm a few years ago, but the company plans to mass produce infolding foldable OLED to minimize damage to the screen from December.

Since Royole has not yet produced products with oxide TFT, the company has not achieved complete TFT reliability. Because of very low yield for the time, the available supply volume is expected to be limited even if the sales begin.

Reporter & Analyst : Daejeong Yoon

Japan, which used to be the strongest country in display industry in the past, gradually declined through the era of CRT, PDP and LCD, and has fallen to the third-largest producer in OLED industry after China.
Currently, Japanese companies that produce AMOLEDs are Sony and JOLED. Both companies are producing OLED for special monitors at 500 ~ 1,000 units per month. Although JDI has developed flexile OLED, it has not commercialized yet.

Sharp has challenged the OLED market for smartphones in the current Japanese manufacturing environment, which was passive in production. The production of flexible OLED is to be started at the 4.5 generation production equipment of Sakai plant. The flexible OLED is scheduled to be adopted on AQUOS zero model for Soft Bank.

The product was exhibited at the Sharp booth of CEATEC 2018, which is a QHD+ 6.2-inch dual edge type. Sharp
Officials said that the sales have not started yet.

 

 

In addition, Sharp also exhibited two types of flexible OLEDs which are under development.

 

OLEDON, is to announce belt-plane source deposition technology for manufacturing ultra-high resolution and ultra-area OLED

Plane source technology, which was first developed by OLEDON in the world, has the principle of depositing the first organic material on the metal surface and evaporating it upwards to produce fine pattern of 2250 ppi, which is ultrahigh resolution. In this plane source process, three processes such as the first deposition, the plane source inversion, and the second evaporation are necessary, and the number of the high vacuum chambers is increased when the mass production is applied. The belt plane source FMM deposition technology introduced by OLEDON has a concept of carrying out the above processes at a time in one evaporation equipment. This is a continuous plane source supplying deposition technology in which the metal surface is formed in a belt shape.

 

Hwang added, “Using vertical plane source enables smooth deposition process for the 12th generation class area substrate for QD-OLED TV without sagging problem. Vertical belt-plane source evaporation equipment adopts the concept of depositing the substrate in a standing-up position so that the load on the framed glass chuck and the open mask is very low. Thus, easy transportation of the substrate, and uniform deposition process of thin film over a very large area in the static state are possible.” This technology is expected to be applicable not only to the 8th generation but also to the cluster type mass-production evaporator with substrate sizes more than 10 generations in the future.

First, Samsung Display emphasized the advantages of OLED by introducing the transition process of full screen OLED and HDR & true black under the theme of ‘realistic multimedia’. Currently, the smartphone market is dominated by full-screen smartphones applied with OLED, and OLEDs are able to display a completely black color compared to LCDs, resulting in a clearer picture quality.

 

The company also introduced the next generation touch technology such as HoD (Haptic on Display; when you touch the screen, you can feel the physical vibration by hand. Thus, you can enjoy the contents realistically.), FoD (Fingerprint on Display) and SoD (Sound on Display) together with full screen technology.

In addition, the front of the booth is equipped with a space to experience the durability of the flexible OLED with a plastic cover window, so that visitors can try to hit the panel with a hammer or drop the ball. Various advantages of flexible OLED have been shown.

 

Moreover, OLED for VR, which implemented 1200ppi ultra-high resolution, automotive rollable display (CID) and 5.9 type transparent HUD were displayed, raising expectations for future development of display technologies.

LG Display unveiled its 8K OLED TV for the first time in Korea, which had been showcased at CES 2018 in Las Vegas earlier this year. This product is the biggest OLED TV that is currently in existence and provides 4 times clearer picture quality than UHD resolution.

Furthermore, LG Display showed the possibility of various OLED applications while the company showcased its 65-inch CSO (Crystal Sound OLED), a sound system built into the panel, and 77-inch UHD wallpaper OLED product that can be closely adhered to the wall to enhance interior effects in the living room.

 

OLEDON unveils plane source deposition technology for ‘super-gap’ OLED manufacturing.

Attention is growing since OLEDON, a venture company developing OLED deposition equipment, unveiled plane source deposition technology for OLED manufacturing to maintain ‘a superb gap with the competing countries’, at IMID2018, held in COEX, Seoul, Oct. 24, 2018.

Hwang Chang-Hoon, CEO of OLEDON, said, “Korea should actively invest in the development of creative deposition technology to maintain the first place in the current OLED producing countries.” He expects that plane source deposition technology is to be used both for small and medium size OLED and large area OLED manufacturing in future.
OLEDON is developing the world’s first curved plane source FMM deposition technology, which is an ultra-high-resolution OLED deposition technology capable of manufacturing 2250ppi AMOLED. The shadow distance of fine pattern can be up to 0.18um, enabling 11K high-resolution AMOLED pattern process.

Room mirror and side mirrors of Smart Car will be replaced by OLED

Japan Electronics Show, CEATEC2018, was held at Makuhari Messe last week. CEATEC JAPAN 2018 is a global showcase for Japan’s growth strategies and vision of the future. Various Japanese companies exhibited products centered on IoT robots and AI. It is recognized that the electronics industry in Japan is gradually shifting from large hardware to small advanced parts and software industries.

In the exhibition, the core technology of smart car was introduced for self driving. Kyocera introduced cockpit technology that can anticipate and prevent various accidents that may occur in blind spots as advanced sensing technology and image processing technology to enhance the safety of automobiles.

 

For automotive display business, the company also exhibited advanced concept cars with clusters, CIDs, room mirror displays and side view displays.

 

According to Kyocera officials, room-mirror and side-view displays that show the external environment might have limitations and need to be converted into OLED displays since all of the concept car’s displays use LCDs.
When LCDs are used for room mirror display and side view display that show rapid changes while driving at high speed, the location of surrounding cars is to be expressed as being behind the actual location, which can result in an accident. In particular, LCDs with low contrast ratio are not able to accurately represent external objects at night.
OLEDs with high-speed response and high contrast ratio are expected to dominate the future automotive room mirror and side view mirror market.

[ICEL 2018] TADF attracts attention as next generation emitting material

In addition to monitors and virtual reality devices, OLED is gradually expanding its domain beyond smartphones and TVs, inclusive of the application of side-mirror OLED in automobiles. As new OLED applications are increased in various environments, it is essential to develop technologies to satisfy users.

In ICEL 2018, which is being held at Jeju International Convention Center from October 15th, many presenters and attendants emphasized that material development is essential to improve the performance of OLED as the OLED market grows more. As an alternative material, TADF (Thermally Activated Delayed Fluorescence) is mentioned.

First, Hwang Seok-Hwan, chief researcher in Samsung Display said that TADF is to be a good resolution as one of emitting materials for new deposition process, referring to the continued growth of OLED panel and material market.

 

 

Hwang said that the efficiency of fluorescent Blue is almost saturated, so 100% luminance efficiency can be obtained theoretically by applying TADF with the advantages of not using expensive rare earth metals. He added that improvement of material stability, improvement of color purity by using boron material, development of host having high triplet energy need to be superseded.

 

Also, CYNORA, a leading TADF developing company, disclosed the performance of dark blue TADF developed so far.

CYNORA said that the luminance efficiency and color purity of dark blue TADF reached the level that the related companies required, and that its current goal is to develop the technology to improve lifetime. In addition, based on this know-how, the company will quickly develop green and red TADF, and now green TADF has been delivered to several customers as a sample.

 

 

Merck confirmed that TADF is the most powerful luminescent material to replace fluorescent Blue at its presentation together with a poster about TADF.

OLED companies and research institutes are focusing attention on whether blue TADF can quickly enter OLED market and upgrade OLED performance further.

 

[ICEL 2018] What are the future challenges for LG Display to improve OLED TV performance?

At ICEL 2018, held at Jeju International Convention Center from Oct. 15, Soo-Young Yoon, Vice President and Head of LG Display Laboratory, presented the challenges for the OLED TV performance improvement and price reduction

 

Yoon said “In 2018, the future prospects of OLED TVs have changed more positively compared to that in 2016. In 2013, only LG Electronics was an OLED TV set maker. The number of OLED TV set makers has steadily increased; ten in 2016, and fifteen in 2018. Many TV set makers are choosing OLED. ”

He added that although OLED TV is on the track of success with lots of improvement, it has to be further developed. The challenge is the improvement for high brightness, color reproduction rate and with the development of 8K resolution. Also he mentioned that the price reduction is to be necessary.

 

 

Yoon explained that the development of components such as driver IC and controller is an important task to develop 8K OLED TV. In order to improve the brightness, color reproducibility, and lifespan, TADF and phosphorescent Blue are to be good alternatives for improving the RGB emitting materials. The enhancement of out-coupling is also important.

In addition, he referred to the solution processed OLED as a technology, to compete against LCD TV price, with the necessity of developing inkjet equipment, process, and soluble materials. For this, it is required to develop the ink jet equipment and shorten the process time for mass production, but the performance and reliability of the soluble materials will be more important.
Finally, he commented that the company will focus on 8K OLED TV and rollable OLED TV with the improvement of brightness until 2020. After 2022, the company will develop the OLED TV which has an enhanced brightness of 300 nits or more, a color gamut that satisfies BT.2020, and a lifespan of more than 30,000 hours.

 

CYNORA announced that it has extended its joint development agreement for TADF commercialization with LG Display.

TADF developer CYNORA has announced that it has extended its joint-development agreement with LG Display. The two companies have been co-developing deep-blue TADF OLED emitters for two years, and have now decided to continue the cooperation towards the commercialization of TADF emitters in OLED displays.

The performance of CYNORA’s latest deep-blue material was presented at IMID 2018 held in August of the year. Among the performance introduced, the CIEy is 0.13, the EQE is 20% based on 1000 nits, and the LT97 is 15 hours at 700 nits.

CYNORA CEO Gildas Sorin commented, “Currently, CYNORA focuses on the development of deep blue TADFs for OLED TVs. Through the accumulated know-how to develop deep blue TADF, it also has plans to develop a light blue TADF for lighting applications and a green TADF for displays.”

The golden market for Automotive OLED Displays is approaching.

The display of connected cars is getting bigger and bigger to for the convenience of providing various information. The displays used in general vehicles include the cluster, CID (center information display), RSE (rear seat entertainment), and RMD (room mirror display). In connected cars, various buttons of the center fascia are displayed, and a display is attached to the door using a camera instead of a side mirror. The Audi e-tron®, all-new electric Sports Utility Vehicle (SUV) feature a small side-view OLED display instead of the existing side mirrors. According to Choong-Hoon Yi, CEO of UBI Research, the reason why automobile manufacturers are actively trying to use OLED displays is because OLED can be a good resolution in various aspects such as design, visibility and thickness. Since the side view camera is attached to the door, the viewing angle should be very good for the driver’s eyes. Especially in nighttime driving, black should be accurately represented on the display to make things clearer. In addition, OLEDs with fast response must be used for the mirror of car because the screen needs to be changed rapidly depending on speed of the car (if it is running at a high speed). In winter season when temperatures are low, LCDs with slow response times are not recommendable to be used.

Flexible OLEDs should also be used to mount the cockpit display on the dashboard that maximizes driver’s convenience.

<BenzのF015 cockpit displayとAudiのe-tron side view display>

In contrast, LG Display, the strongest player in the market for OLED TVs, is looking for the display market for clusters and CIDs as flexible OLED with two layers of RGB OLED. Visteon, the second-largest supplier of automotive displays, is preparing for the cluster market with LG Display’s pOLED. Since 12.3-inch p OLED is made of LTPS substrate and its OLED process is more complicated than that of OLED for smartphone, panel prices including module are expected to be equal to 55-inch WRGB OLED, which can create a premium market even if the quantity is small.

<Visteon, 12.3 inches pOLED>

According to “Automotive OLED Display Report” published by UBI Research, the market for automotive OLED displays led by Samsung Display and LG Display is expected to grow to US$ 540million in 2023.

Samsung Display, supplies 7-inch OLED for Virtual Exterior Mirror to Audi

Samsung Display announced on October 3 that the company will be supplying a 7-inch OLED display for Audi’s all-new electric Sports Utility Vehicle (SUV), the Audi e-tron®. The Audi e-tron has attracted attention throughout the automotive industry. One of its highlights are optional* ‘virtual exterior mirrors’ – a ‘first’ for a volume-production car.

Audi’s virtual exterior mirrors feature a small side-view camera instead of the existing side mirrors. The driver can view the images captured by the camera in real time through the OLED display installed between the vehicle’s A pillar (the column next to the front glass) and the door

<Virtual exterior mirror applied to e-Tron, Audi, Source: news.samsungdisplay.com>

The OLED display supplied by Samsung Display is equipped with one camera on each side of the vehicle dashboard, replacing the existing side mirror function, and the built-in touch sensor allows people to zoom in or out on the screen as if to manipulate a smartphone. Audi said the Virtual Exterior Mirror offers a wider field of view without blind spots, compared to a typical side mirror. It provides better visibility even on cloudy days and in dark places, and it provides a ‘view mode’ suitable for each driving situation such as highway driving, rotation, parking, etc for more convenient and safe driving. By eliminating the side mirrors that protrude out of the vehicle, it reduces air resistance and wind noise. Also, slim and beautiful design is possible, reducing the body width by 5.9 inches.

The images seen on the Samsung display that covers each virtual exterior mirror appear natural and distinct with none of the drag effects typically triggered by a slow response rate at low temperatures, while exhibiting outstanding color reproducibility. The Samsung 7-inch OLED display provides Audi e-tron drivers with an ideal visual solution, thanks to its low power consumption and innovatively thin, lightweight design, in addition to its superior imaging.

Jeeho Baek, Senior Vice President of Samsung Display, said “It is inspiring to many that our OLED display is used in Audi’s virtual exterior mirror, demonstrating that Samsung OLED technology is being optimized for cutting-edge automobile systems around the world. We will continue to actively support leading automotive manufacturers in helping them to advance the future automotive market through the use of our OLED display technology with its high resolution, advanced designs and low power consumption.”

OLEDON develops vertical plane source deposition technology for large OLED TV manufacturing

Hwang Chang-Hoon, CEO of OLEDON, which has developed plane-source deposition technology for small & medium-sized OLED and large area OLED, said that it is under development of vertical plane source deposition technology capable of manufacturing ultra-large OLED TVs of 77 inches or larger. Hwang introduced the related technology that it is possible to mass produce OLED TVs of 77 inches or more without the sagging problem of large substrate such as 12th generation (3300 x 4000 mm) substrate when using vertical plane source deposition technology.

According to Hwang, the production yield for 75 inch TVs or larger with the conventional inline type evaporator might be very low due to severe sagging of the substrate and difficult control of many linear sources. To solve this problem, Hwang said that a new 12-generation large-area cluster-type deposition technology is needed, and that vertical plane source deposition technology will be an appropriate alternative.

On the other hand, OLEDON holds the original patents for plane source deposition technology. It also filed a patent related to the curved plane source FMM deposition for high-resolution AMOLED manufacturing, and a patent related to the vertical plane source deposition technology for manufacturing large-area OLED TV.

프리미엄 TV존 OLED TV와 Micro LED?

2분기 실적 갱신을 하며 OLED TV 덕을 톡톡히 보고 있는 LG전자에 비해 삼성전자는 최근 프리미엄 TV 시장에서 고군 분투하고 있다. 마케팅을 앞세워 QD-LCD로 프리미엄 TV 시장에서 대응해 오다 점차 그 힘을 잃고 있는 것으로 보인다. 2017년부터 IFA, CES등 가전 전시회에서 QLED TV 개발 발표, 프라이빗 부스 전시 등 새로운 시도를 하고 있지만 개발이 더딘 와중 삼성전자의 Micro LED 상용화의 공식 발표로 향후 프리미엄 TV 시장의 구도에 대한 관심이 뜨겁다.
2018 CES와 2018 IFA에서 대중에 공개한 삼성전자의 Micro LED (Mini LED) TV “The Wall”은 상당 수준 발전한 Micro LED 기술을 보여주고 있으며 이에 따라 대만의 관련 업체 들의 주가도 높아지고 있다. 이런 흐름에 대응하는 차원에서 2018 IFA에서 LG전자도 173인치의 Micro LED TV를 전시한 것으로 보인다.

넓은 시야각, 완벽한 블랙의 표현, 빠른 응답 속도 등이 OLED TV의 장점으로 언급되며 프리미엄 TV 시장을 점유해 가고 있다. 산업에서는 아직까지는 Micro 수준이라고 할 수 없는 픽셀을 더 줄이고 가격을 경쟁 가능한 수준으로 하락, 전사에서 오는 신뢰성을 극복하는 등의 한계점 들을 극복한다면 150인치 정도의 초대형 디스플레이 시장을 형성할 수 있을 것으로 예상하고 있다. 이론적으로 Micro LED는 OLED 와 같이 RGB가 스스로 빛을 내는 자발광 디스플레이이며, 작은 부피와 높은 명암비, 사이즈를 줄임으로서 단위 면적당 더 많은 화소수를 넣을 수 있어 고해상도 구현에 유리하다. 또한, 초소형 픽셀사이즈로 구부러지는 디스플레이 구현도 가능한 것으로 알려져 있다.
하지만 여전히 가정용 TV로 생산하기에 Micro LED 는 제조 비용의 문제와 발열등 극복해야될 한계점을 가지고 있어 본격적인 상용화 까지는 시일이 꽤 걸릴것으로 내다 보고 있다. 각종 전시회에서 지속적으로 발전된 제품을 공개하고 있는 만큼 산업의 기대도 큰 것으로 보인다. 또한 동시에 OLED TV 또한, CSO(Crystal Sound OLED) 등 다양한 각도로 진화하고 있어 앞으로의 프리미엄 TV 시장이 기대된다.

Apple이 현지시간으로 9월 12일 미국 캘리포니아주에 위치한 애플 파크 스티브 잡스 극장에서 이전보다 더 큰 화면에 헬스케어 기능을 강화한 Apple Watch Series 4를 발표했다.

<Apple Watch Series 4, Source: apple.com>

Apple은 이번 발표에서 Apple watch Series 4에 LTPO라는 새로운 기술을 도입해 전력 효율을 향상시켰다고 밝히며 이목을 끌었다.

LTPO는 low temperature polycrystalline oxide의 약자로써, 전하 이동도가 우수한 poly-Si과 저전력 구동이 용이한 IGZO의 장점만을 활용한 TFT의 일종이다. LTPO TFT는 누설전류가 적고 on/off 특성이 좋기 때문에 소비 전력이 낮고 배터리의 지속 시간은 늘어난다.

<Apple의 LTPO TFT 특허>

또한, Apple은 Apple Watch 4의 본체 규격을 40mm와 44mm로 키우고 bezel을 좁혀 이전 모델들에 비해 display area를 35%와 32%로 늘렸으며, 화면 해상도도 44mm 모델은 368×448 픽셀, 40mm 모델은 324×394 픽셀로 증가시켰다고 설명했다. Apple Watch4의 디스플레이는 LG디스플레이에서 제작한 plastic OLED이며 최대 밝기는 1,000 nit이다.

Apple Watch Series 4의 출시 가격은 GPS 모델이 399달러부터이며 셀룰러 모델이 499달러부터다. 예약 주문은 9월 14일부터 진행되고 제품 출시는 21일부터다.

IFA 2018 TV 전시 동향

2018 8 30일부터 9 5일까지 베를린에서 유럽 최대 가전 전시회인 IFA2018이 개최되었다. IFA2018에서 전시된 TVOLED TV를 비롯하여 LCD TV micro LED TV, laser TV 4종류가 있었으며, 전시 참가 업체는 삼성전자, LG전자, 소니, 파나소닉, 샤프, 도시바, TCL, 하이센스, 창홍, 필립스, 베스텔, 메츠, 그룬딕, 레베 등이 있었다.

유비리서치는 IFA2018에 전시된 전세계 주요 TV 업체들의 전시 제품을 조사하여 OLED TV를 중심으로 전시 동향 분석 보고서를 출간하였다.

본 보고서에 따르면 IFA2018에서 TV 전시 주요 특징은 75인치 LCD TV 부상과 8K TV, micro LEDTV 세가지로 요약되었다.

첫째 LCD TV75인치가 중점적으로 부각된 이유는 65인치 LCD TV 가격 하락으로 2,000달러 이상의 프리미엄 TV시장에서 수익을 내기 위해서는 75인치 이상의 LCD TV가 필요해졌기 때문이다. 삼성전자 부스에서는 75인치가 65인치에 비해 차이가 별로 나지 않음을 홍보하였다.

두번째 특징은 8K TV이다. 이전 전시회까지는 샤프만이 8K LCD TV를 전시하여 왔으나 IFA2018에서 삼성전자가 8K LCD TV (QLED TV)를 처음으로 전시하며 많은 관람객을 끌었다. 88인치 8K OLED TV도 처음으로 LG전자 전시장에서 공개되었다. 완벽한 블랙과 OLED만의 생동감 있는 화면에 8K 고해상도가 겹쳐 가장 현실감이 있는 TV로 인정받았다. 8K LCD TV는 삼성전자와 샤프 이외에도 베스텔에서도 전시되었다.

<삼성전자 8K QLED TV>

He revealed its performance, adding that CYNORA has been carrying out the necessary research to make the lifetime of deep Blue as long as that of sky Blue even with phenomenon that the life span is getting longer as the Blue goes closer to the sky Blue

Fluorescent blue is currently used for the Blue of all OLED applications. Attention is growing whether Blue TADF or Blue Fluorescence can be commercialized to realize better efficiency and lifetime than existing fluorescent blue.

[IMID 2018] Samsung Display, The key material that will connect the smart world and the individual in the future is the display

Reporter & Analyst : Daejeong Yoon

At IMID 2018 held in BEXCO, Busan, Korea on August 29, Kwak Jin-Oh, vice president of Samsung Display, delivered a keynote speech on the theme of ‘The Infinite Evolution with Display’. He emphasized “Display will be the key material to link to the smart world and the creation of a new world and environment will be accelerated.”

Comparing the evolution of living things with the evolution of displays, Kwak pointed out the direction of the next-generation displays such as ‘size diversity from small to large size, adaption in design inclusive of full screen and flexible, and convergence with other technologies’.

In terms of size diversity, Kwak said, “High-resolution displays that can feel realism in small and medium-sized area, and displays that can be immersed like a big screen in a movie theater in large area, are required.”

The design adaptation then was referred to design autonomy as one of the values of next-generation displays. He further emphasized the value of rollable and stretchable displays as well as foldable displays in small and medium sized displays.

Kwak said that Samsung is developing rollable displays as well as foldable displays that are currently attracting great interest. Unlike foldable display, rollable display requires consideration of the stress on the front of the panel. He commented “Because there are many things to consider such as the time when it is rolled up, and the number of times it is rolled and unrolled, the company is conducting research to solve them.”

He also introduced a stretchable display that can implement patterns freely, and explained that it is developing various structures using RGB pixel unit and stretchable unit to implement displays that have high reliability with low stress.

Mentioning about biotechnology at the convergence area, he pointed out that new fusion technologies need to be considered such as measurement of oxygen saturation by transmitting light to hemoglobin or changes in the wake up mode and sleep mode of the display depending on the melatonin change.

Finally, Kwak concluded that display is evolving to create a new society and environment, emphasizing that display is the key material to link between the individual and the smart world in the forthcoming 5G era.

[IMID 2018] LG Display, showcased 2-stack RGB OLED for automobile OLED with improved life span.

At IMID 2018 held in BEXCO, Busan on August 29, Kim Kwan-Soo, research fellow of LG Display presented about a new OLED technology for automotive displays.

Kim said that RGB OLEDs applied to mobile devices and WRGB OLEDs applied to TVs do not satisfy customers’ needs in terms of life span. To solve this issue, he introduced 2 stack RGB OLED in which RGB OLED has the same tandem structure as WRGB.

Because 2 stack RGB OLED can be thick due to adding a layer of CCL (charge generation layer) to the multi-layer structure, HTL is made thinner than before and the charge balance of the emitting layer is optimized.

As a result, the 2-stack RGB OLED shows 1.5 ~ 2 times higher emitting efficiency than the 1-stack RGB OLED. Its lifetime is increased by 4 times on T80 basis.

However, the 2-stack structure has a disadvantage in that it has higher power consumption than the general structure. Thus, it is necessary to make efforts to solve this disadvantage.

[IMID 2018] LG Display and Samsung Display exhibited a large number of large, and small & medium sized OLED applications.

LG Display and Samsung Display introduced a number of applications using OLED at IMID 2018 held in BEXCO, Busan, drawing attention from many visitors. In particular, LG Display displayed its strategies mostly for large OLED applications such as 77-inch transparent OLED and 55-inch video wall OLED, while Samsung Display introduced the small and medium sized OLED applications mainly for automotive and virtual reality devices.

First, the panel thickness of the 77 inch transparent flexible OLED introduced by LG Display is 400 μm, the bending radius is 80 mm, and the luminance is 200 nit based on full white.

LG Display explained that it would improve the required transmittance and durability. Also, it commented that the goal is to reduce bezel to 0.5 mm at its display of 4 FHD OLEDs with 3.8 mm bezel.

In addition, LG Display presented a 1200ppi 4.3-inch WRGB OLED for virtual reality devices. One official explained that WRGB OLED, which represents the resolution by etching the color filter, would be advantageous for higher resolution than RGB using the deposition method.

Meanwhile, Samsung Display exhibited a number of automotive OLEDs, including unbreakable OLED for 6.22 inch steering wheel, 1000R curved OLED for passenger monitor, transparent OLED for HUD, S-curved OLED for CIO and rollable OLED. The concerned official expects the OLED to be widely applied to inside automobiles because it has excellent design autonomy, compared to LCD.

He added “Although there are many things to be improved, such as brightness and reliability, it is continuously improving the required performance through the feedback from European customers”.

Furthermore, Samsung Display showcased light field display and 2,000ppi resolution RGB OLED for virtual reality devices.

[IMID 2018] OLEDON, developed ‘curved plane source FMM deposition technology’ for 2250ppi AMOLED for the first time in the world

OLEDON is a company which develops plane source deposition technology for high resolution AMOLED manufacturing. Hwang Chang-Hoon, CEO of  OLEDON announced in IMID 2018 that it developed ‘curved plane source FMM deposition technology’ that can be adopted to 2250ppi AMOLED pixels, for the first time in the world.

Conventional linear source FMM deposition technology has a shadow distance of 3um. The available production range is 570ppi AMOLED resolution. On the other hand, the plane source deposition technology already demonstrated in OLEDON can achieve a resolution of 800 to 1200 ppi of AMOLED with a shadow distance of 0.8 to 1.5 μm. Meanwhile, the newly developed ‘curved plane source FMM deposition technology’ is an upgraded technology of the plane source deposition technology which can realize the maximum resolution of AMOLED to 2250ppi with a shadow distance of 0.18 ~ 0.6μm.

The principle is that light is gathered through a concave mirror, a curved surface is applied to the conventional flat plane source, and the light emitting material does not spread, but is precisely deposited at a desired position, thereby reducing the shadow distance.

If this technology is commercialized, it is expected that it can be widely applied not only to mobile devices but also to virtual reality devices.

소니 모바일에도 OLED 탑재

OLED TV로 프미리엄 TV 사업을 성공적으로 부활시킨 소니가 모바일에도 OLED를 탑재했다. 기존의 Xperia 시리즈와 유사한 살짝 굴곡있는 유리 뒷면과 6인치 디스플레이를 채택했다. 뒷커버의 디자인을 두고 소니는 삼성과 애플등과 비교했을 때 손에 잡기 쉽도록 했다고 발표했다. 최근 iPhone의 M자형 디자인과 유사한 디자인의 스마트폰이 출시되고 있는 것과 비교, 소니는 뒤쪽 하단에 작은 홈을 만들었다. 이 홈의 기능에 대해서는 아직 알려진 바가 없으나 디자인 차별성의 의미로 해석해 본다.

경쟁사의 OLED 채택 스마트폰 출시에 비해 많이 늦었지만 스크린 사이즈를 최대한으로 키우고, 가장 경쟁력 있다고 할 수 있는 부분인 색감, 색재현율 등에서 많은 노력을 하였다. 19메가 픽셀 센서 카메라에는 최근의 트렌드를 반영하며 AI 기능을 더했고 사용자의 편리성을 위해 물리적 버튼도 동기화 했다. Xperia XZ3의 마케팅 포인트 중 하나는 점점 디스플레이 사이즈가 커짐에 따라 한손으로 동작하기 불편함에 대해 “한손으로 동작가능한 디자인”으로 보인다. 디스플레이의 끝 부분에 두번 탭을 통해 바로가기 메뉴등을 실행할 수 있도록 했다. Xperia XZ3은 2018년 9월 말부터 한국을 제외하고 다양한 국가 및 지역에서 출시될 예정이다.

OLED TV에 이어 소니의 감성을 담은 스마트폰을 기다려온 소비자들에게는 신규제품에 대한 희소식이고, 디스플레이 산업에 또한 그동안 모바일 사업에서 부진을 겪어온 소니가 OLED 채용으로 TV사업에서와 같은 부활을 할 수 있을지 지켜 볼 수 있는 제품이 아닐까 생각한다.

[IMID 2018] 청색 TADF와 hyperfluorescence, 효율과 수명 두 마리 토끼 모두 잡을 수 있을까

8월 31일 부산 BEXCO에서 열리고 있는 IMID 2018에서 Kyulux의 CEO, Junji Adachi는 기존의 형광재료 host와 dopant에 TADF dopant를 첨가하는 hyperfluorescence의 성능들을 공개했다.

Junji Adachi가 공개한 노란색 hyperfluorescence의 색좌표는 (0.49,0.50), 반치폭은 76 nm, 1,000 nit 기준 EQE는 15.7%, 1000 nit 기준 LT50은 6만 2천시간이며, 녹색 hyperfluorescence의 색좌표는 (0.28,0.65), 반치폭은 31 nm, 1000 nit 기준 EQE는 20.6%, 1,000 nit 기준 LT50은 4만 8천시간이다.

이 자리에서 Junji Adachi는 현재 개발 중인 청색 hyperfluorescence의 성능도 공개했는데, 최대 발광 파장은 470 nm, 1000 nit 기준 EQE는 22%, 750 nit 기준 LT50은 100시간이라고 밝혔다. 특히, 2018년 상반기부터 청색 hyperfluorescence의 성능이 빠른 속도로 향상되기 시작했다며 앞으로 성능이 더욱 더 향상 될 것으로 기대했다.

이어진 발표에서 CYNORA의 Dr. Georgios Liaptsis는 현재 개발 중인 진한 청색(deep blue)을 설명하며 파장은 460 nm, CIEy는 0.15 이내가 되야 한다고 강조했다. 연한 청색(sky blue)로 갈수록 수명이 길어지는 특징이 있는데, CYNORA는 진한 청색으로 연한 청색만큼의 수명을 가질 수 있도록 연구를 진행하고 있다고 설명하며 성능을 공개했다.

현재 모든 OLED application의 청색은 형광 청색이 사용되고 있다. 청색 TADF나 청색 hyperfluorescence가 상용화 되어 기존의 형광 청색보다 더 개선 된 효율과 수명을 보여줄 수 있을지 귀추가 주목된다.

[IMID 2018] LG Display와 Samsung Display, 다수의 대형과 중소형 OLED application 전시

LG DisplaySamsung Display가 부산 BEXCO에서 열리고 있는 IMID 2018에서 OLED를 활용한 다수의 application을 선보이며 관람객들의 이목을 집중시켰다. 특히, LG Display77인치 transparent flexible OLED55인치 video wall OLED 등 대형 OLED application 위주로 전시한 반면, Samsung Display는 자동차용과 가상현실 기기용 OLED 등 중소형 OLED application을 주로 선보이며 뚜렷하게 서로 다른 사업 전략을 선보였다.

먼저, LG Display에서 77 inch transparent flexible OLED의 패널 두께는 400 um, 곡률 반경은 80 mm, 휘도는 full white 기준으로 200 nit. LG Display는 부족한 투과도와 내구성을 더 개선시킬 것이라 언급했다. 또한, 3.8 mm narrow bezel을 가진 4장의 FHD OLED를 전시하며 bezel0.5 mm 까지 줄이는 것이 목표라고 설명했다.

이 밖에 LG Display는 가상현실 기기용 1200ppi 4.3 인치 WRGB OLED를 선보였다. 관계자는 color filter를 에칭하여 해상도를 나타내는 WRGB OLED가 증착 방식을 이용하는 RGB보다 고해상도에 유리할 것이라고 설명했다.

한편, Samsung Display6.22인치 steering wheelunbreakable OLED와 동승자 모니터용 1000R curved OLED, HUD용 투명 OLED, CIDS-curved OLED, rollable OLED OLED를 활용한 다수의 자동차용 OLED를 전시했다. 업체 관계자는 OLEDLCD보다 디자인 자율성이 매우 뛰어나기 때문에 자동차 내부에 폭 넓게 적용될 수 있을 것이라 기대했다.

 

 

아직 개발 중인 단계로 휘도와 신뢰성 등 개선해야 할 사항은 많지만, 현재 유럽의 고객사들과의 피드백을 통해 지속적으로 성능을 개선하고 있다고 설명했다.

이 밖에, Samsung Displaylight field display와 가상현실 기기용 2000ppi 해상도의 RGB OLED 등을 선보였다.

 

[IMID 2018] OLEDON, 2250ppi AMOLED 제조용 곡면소스 FMM 증착기술 세계최초로 개발

고해상도 AMOLED 제조용 면소스 증착기술을 개발하고 있는 OLEDON의 황창훈 대표는 2250ppi AMOLED 화소의 증착이 가능한 곡면 소스 FMM 증착기술을 세계 최초로 개발하였다고 IMID 2018에서 발표했다.

기존의 리니어 소스 FMM 증착기술은 섀도우거리가 3 um으로서 생산 가능한 AMOLED의 해상도는 570ppi 수준이다. 반면, OLEDON에서 이미 선보인 바 있는 면소스 증착기술은 섀도우거리가 0.8~1.5 um 으로서 AMOLED의 해상도를 800~1200ppi까지 구현할 수 있다. 한편, 이번에 새로 개발된 곡면소스 FMM 증착기술은 섀도우거리가 0.18~0.6 um로서 AMOLED의 최대 해상도를 2250ppi까지 구현 가능한 면소스 증착기술의 업그레이드 기술이다.  

원리는 오목거울을 통해 빛을 모으는 것처럼, 기존의 평평한 면 소스에 곡면을 가해 발광재료가 퍼지지 않고 원하는 곳에 정확히 증착 되어 섀도우 거리를 줄일 수 있는 방식이다.

이 기술이 상용화 된다면 mobile 기기 뿐만 아니라 가상현실 기기 등 폭넓게 적용될 수 있을 것으로 기대를 모으고 있다.

[IMID 2018] LG Display, 수명을 개선한 자동차용 OLED로 2 stack RGB OLED 선보여

829일 부산 BEXCO에서 열린 IMID 2018에서 LG Display의 김관수 연구위원(research fellow)은 자동차용 디스플레이에 적용될 새로운 OLED 기술에 대해 발표했다.

김 연구위원은 현재 모바일 기기에 적용되고 있는 RGB OLEDTV에 적용되고 있는 WRGB OLED는 수명 측면에서 고객사들의 요구를 만족시키지 못하고 있기 때문에, 이를 해결하기 위한 방법으로 RGB OLEDWRGB처럼 tandem 구조를 갖는 2 stack RGB OLED를 소개했다.

2 stack RGB OLED는 다층구조에 CGL(charge generation layer) 층이 더해져 두께가 두꺼울 수 있기 때문에 HTL을 기존보다 얇게 만들고 발광층의 charge balance를 최적화하였다.

그 결과 1 stack RGB OLED보다 1.5배에서 2배 향상된 발광효율과 함께 수명이 T80 기준으로 4배 이상 증가하는 효과가 나타났다고 보고했다.

하지만 2 stack 구조는 일반 구조에 비해 소비 전력이 높은 단점이 있어 이를 해결하기 위한 노력이 필요하다고 지적했다.

[IFA2018] 엘지전자 88인치 OLED TV 최초 공개

유럽 최대 가전 전시회인 IFA의 엘지전자 TV 부스는 역시 OLED가 TV의 주력을 차지하였다. CES2018에는 전시되지 않았던 88인치 8K OLED TV가 공개상에서 최초로 모습을 드러내었다.
88인치 8K OLED TV는 OLED의 화려한 색상과 완벽한 블랙에 초고해상도가 더해져서 입체감이 한층 살아난 최상의 TV임을 보여주고 있다. 엘지전자 관계자에 의하면 프리미엄 TV 해상도가 4K를 넘어 이미 8K 시장으로 진입을 시작했기 때문에 OLED TV도 이에 대응할 수 있는 제품이 필요한 시기가 되었다고 언급했다.
LG디스플레이는 88인치 이외 75인치와 64인치 8K OLED 패널을 개발중에 있으며 내년에는 이들 제품들이 모두 시장에 나올 수 있을 것으로 기대된다. 현재 개발중인 8K OLED 패널은 모두 bottom emission 구조이다.

 

엘지전자는 CES2018에서 화질 프로세스 알파9으로 좋아진 OLED TV의 화질 소개에 중점을 두고많은 장소를 할애하였으나 88인치 8K OLED에 장소를 양보하고 간결하게 전시 공간을 꾸몄다.

OLED TV 성능 소개를 “Crisp and Smooth Motion”과 “Clean, Sharp, and Vibrant Images” 두 가지로 압축하였다. 이들 성능들은 화질 분야에서 최고로 인정받고 있는 소니와 경쟁할 수 있는 수준에 도달하였음을 나타내고 있다.

JOLED 470억엔 조달, 자동차용 solution process OLED 사업 박차 가한다.

세계 최초로 solution process OLED 제품화에 성공한 JOLED가 23일 제 3자 할당 증자로 총 470억엔을 조달했다고 발표했다.

JOLED에 따르면 Denso가 300억엔, Toyota Tsusho가 100억엔, Sumitomo chemical이 50억엔, SCREEN Finetech Solutions이 20억엔을 투자할 것이며, Denso와는 자동차용 디스플레이 개발을, Sumitomo chemical과는 solution process용 OLED 재료 개발에 협력 할 것으로 알려졌다.

특히 Denso는 그 동안 자동차용 디스플레이용으로 주로 TFT-LCD를 사용했으나, 이번 투자를 통해 가볍고 곡면화가 용이한 OLED를 자동차 내부에 적용하기 위한 개발에 앞장 설 것으로 기대를 모으고 있다.

이번 자금 조달을 통해 JOLED의 solution process OLED 양산을 위한 생산 체제 구축이 가속화 될 것으로 기대된다. JOLED는 7월 1일에 이시카와현 노미시에 ‘JOLED 노미 사업소’를 개설하고 2020년 가동을 목표로 하고 있다고 밝힌 바 있다.

주력 생산 제품은 자동차나 하이 엔드 모니터용 중형 (10~32 인치) solution process OLED로써, 지난 3월 유비리서치가 개최 한 2018 OLED Korea conference에서 Toshiaki Arai chief technologist는 solution process OLED로 중형 OLED 시장을 공략할 것을 밝히기도 했다.

전면지문인식 풀스크린 스마트폰 경쟁 시작

<전면지문인식을 탑재한 디스플레이가 적용된 VIVO의 스마트폰, Android authority>

스마트폰의 전면지문인식경쟁이 뜨거워질 것으로 예상된다.

기존 홈버튼이 있는 스마트폰에는 홈버튼에 전면 지문인식 센서를 탑재하여 제품이 출시되었다. 지문을 이용한 보안강화로 소비자들의 큰 호응을 얻었지만 최근 홈버튼이 없는 풀스크린 스마트폰 위주로 제품이 출시가 되며 지문인식 센서도 스마트폰의 뒷면으로 옮겨졌다. 이로 인해 지문인식 센서에 손가락을 터치할 때 불편한 손모양과 옆에 위치한 카메라렌즈에 지문이 묻는 등 단점이 발생했다.

이러한 점들을 개선하고 완벽한 풀스크린 스마트폰을 제조하기 위해 전면지문인식을 디스플레이와 일체화 시키려는 개발이 지속되고 있다.

전면 지문인식은 크게 광학식과 초음파식이 검토되고 있다. 광학식은 가격이 저렴하고 양산에 용이하지만, 센서가 OLED panel 하부에 위치해야 하므로 OLED 기판이 투명해야한다. 따라서 glass를 기판으로 사용하는rigid OLED에는 적용이 가능하지만 유색PI를 기판으로 사용하는 flexible OLED에는 적용이 어려운 상황이다. 초음파식은 정확성과 내구성이 가장 안정적이지만 제조가격이 비싸다는 단점이 있다.

현재 중국 set업체들은 광학식 전면 지문인식을 채택한 스마트폰 출시를 시작하였으며, 삼성전자에서 내년 출시예정인 galaxy S10에 초음파식 전면지문인식을 채택 여부가 관심을 모으고 있다. 또한 LG 디스플레이도 전면지문인식을 탑재한 디스플레이를 개발 중에 있는 것으로 알려졌다.

이처럼 풀스크린에 전면지문인식을 탑재한 스마트폰 출시가 본격화 될 것으로 기대되는 가운데 하반기 스마트폰 시장의 경쟁이 더욱 치열해 질 것으로 기대된다.

Samsung Electronics, Display Business division’s operating profit in the second quarter of 2018 was KRW 140 billion.

Samsung Electronics announced its sales of KRW 58.48 trillion and operating profit of KRW 14.87 trillion through the earnings conference call of the second quarter, 2018 on July 31. Its sales decreased by 4% YoY and the operating profit increased by KRW 800 billion. Sales decreased 3% QoQ and operating profit fell by KRW 800 billion QoQ.

According to Samsung Electronics, the display panel business recorded sales of KRW 5.67 trillion and operating profit of KRW 140 billion, due to slowing demand for flexible OLED panels and declining sales of LCD TV panels. Despite improved utilization of rigid OLED, OLED division’s earnings declined QoQ due to continued weak demand for flexible products.

Competition with LTPS LCD is expected to intensify at rigid OLED in the second half of 2019, but earnings are to improve on increased sales following the recovery of flexible product demand. Sales and operating profit are projected to improve in the second half on the back of production of flexible OLED for Apple’s new iPhone models from 2Q.

Samsung Electronics plans to expand its share of OLEDs for mobile devices by strengthening its differentiated technology and cost competitiveness, and to strengthen its capacity for new products such as foldable OLEDs. Samsung official said that foldable OLED will contribute to growth from next year rather than immediate performance in the second half of the year.

IT • Mobile (IM) division posted sales of KRW 24 trillion and operating profit of KRW 2.67 trillion. Operating profit fell 34.2 percent from KRW 4.06 trillion in the same period a year ago, and also fell sharply from the previous quarter (KRW 3.77 trillion). In 2Q, handset sales reached 78 million units, of which 90% are smart phones. 5 million units of tablet were sold. The average selling price (ASP) of the handsets is in the second half of US$ 220. The Consumer Electronics (CE) division posted sales of KRW 10.4 trillion and operating profit of KRW 510 billion in the second quarter of the year. Overall sales and operating profit of the first half of the year were KR W 20.14 trillion and KRW 0.79 trillion, respectively. TV profits improved thanks to robust sales of high value-added products such as QLED TVs amid the global sports events. On the other hand, SEC’s facility investment in the second quarter was KRW 8 trillion. By business, semiconductor area accounted for KRW 6.1 trillion and KRW 1.1 trillion was invested for display area. In the first half, a total of KRW 16.6 trillion was invested; including KRW 13.3 trillion in semiconductors and KRW 1.9 trillion in display.

LG Display, Showed OLED lighting for unmarried mothers

LG Display delivered 30 OLED lighting units, made by its employee volunteers, and baby products to 30 unmarried mothers.

This volunteer activity was carried out by the talent services of OLED lighting employees. OLED lighting business division donated 30 flexible OLED lighting panels, and the product planning team customized the lightings for breastfeeding for unwed mothers.

On July 27, the employee volunteers assembled light fixtures, which were customized by woodworking parts through social enterprises, and panels as finished products. In addition, various items needed for a baby and cheer letters for the unwed mothers were packed together. The packaged gift sets were delivered to 30 unmarried mothers living at the unmarried mothers’ facilities through the Eastern Social Welfare Society on July 30.

OLED lighting reduces light flickering and blue light, which affect eye health. And its mild light protects you from eye fatigue. It is also regarded as an eco-friendly product because it generates less heat and has no harmful substances. Since it is the organization that best knows the characteristics of OLED lighting, it suggested the service of delivering the OLED lighting for breastfeeding, made by its members, suitable for the baby-care environment.

Kim Yong-Jin, manager of the OLED lighting sales team who participated in the volunteer service, said “I feel it was worthwhile to deliver the OLED lighting directly to the necessary neighbors although I have dealt with it for business. When I see the neighbors who were delighted with little help, I have to think once again that service activity is so much fun.

How much will be the investment cost for 8Generation QD-OLED TV?

In the “2018 OLED Equipment Report” recently published by UBI Research, the required investment cost was analyzed for the QD-OLED that Samsung Display started to develop.

QD-OLED, which is being developed by Samsung Display, is a method of displaying three colors of RGB by separating green and red from the light emitted from blue OLED through QD (quantum dot) material. The light passing through the QD material once again passes through the color filter and displays a richer color.

QD-OLED is similar to the manufacturing method of WDRGB OLED produced by LG Display. First, both companies use oxide TFTs. At WRGB OLED, blue is applied twice and red and green are deposited between them. In contrast, QD-OLED is fabricated by depositing only blue material twice. Both methods use the open mask with an empty center.

For both QD-OLED and WRGB OLED, the color filter manufacturing cost is assumed to be same; however, QD-OLED should be equipped with additional equipment to coat QD materials.

According to the report, it is expected that the investment cost is to be equal because the similar equipment can be used for module, cell, encapsulation and evaporator. Since WRGB OLED is bottom emission type, it is formed together when backplane is formed including TFT. However, QD-OLED adopts top emission method. A color filter is separately formed on the top glass substrate and the QD layer is patterned thereon. Therefore, QD-OLED requires higher investment cost than WRGB OLED.

The report describes that based on 8Generation 26K, the investment cost for QD-OLED is estimated to be US$ 1.1 billion, which is 1.03 times higher than WRGB OLED (US$ 1.07 billion). In contrast, the required investment cost to manufacture OLED by inkjet method, which JOLED is promoting commercialization, is projected as US$ 0.88 billion, which is to be about 80% of QD-OLED.

UBI research just issued 2018 2Q AMOLED Display Market Tracks

UBI Research recently published “2Q18 AMOLED Display Market Tracks”, which includes market updates of the second quarter of 2018. The report covers OLED display panel makers’ investment status, OLED display market forecasts from 2018 to 2022, OLED demand and supply trends, and competitiveness analysis of OLED Smartphone business for Samsung Display and other OLED display panel makers.

The market update, published with the Excel spreadsheet, describes the production line status and the added line status through future investments of the 15 OLED display panel makers worldwide. Also, it describes not only the major OLED application market such as smart phones and TVs, but also the market forecast by country.

The demand for OLED mobile sets (including smart phones and smart watches) in the first quarter of 2018 dropped to 98 million units from 130 million units in the fourth quarter of last year, due to the lower-than-expected performance of the premium smartphone market, where Samsung Electronics’ Galaxy S series and Apple’s iPhone occupy most of the market. OLED mobile set market is to recover gradually until 3Q, when Apple’s new smartphone model is launched, and by the end of 2018, the demand is expected to recover as to the similar level of the same period of last year. In addition, Samsung Display is anticipated to have a positive impact on the recovery of the Smartphone market in the second half of the year by securing competitiveness by lowering the sales price of rigid OLED panel for mobile phone to about US$ 25 to compete with LCD in China.

Consumers' smartphone replacement cycle is getting longer due to the reason that there is no revolutionary change in the new model compared to the past, and the Smartphone penetration in most of the countries except for India, South America and Africa is reaching the limit. Accordingly, the outlook for the downturn is mostly forecasted in the recent smartphone market. There is a growing interest in technology and design to apply a different form factor to revive the market. In this regard, Samsung Electronics' foldable OLED smartphone, which is scheduled to be released later this year or early next year, is expected to create a new momentum. Attention is focused on whether a folding- type flexible display (Dynamic Flexible Display) will be succeeded as a new type of smartphone from the existing edge-type flexible display (Static Flexible Display).

 

UBI Research predicts that the OLED Smartphone market will grow from 430 million units in 2018 to 900 million units in 2022, and the market for foldable OLED Smartphone is to be from about 1million units in 2019 to 18million units in 2022. This reflects the expansion of OLED panel production lines by panel makers such as LG Display and BOE, besides Samsung Display. It will be updated as new applications are developed in future and the Smartphone market moves forward.

In OLED panel market, OLED panel for Smartphone still occupies 91% of the whole market. Samsung Display has accounted for 90% of total OLED panel market performance and LG Display is followed with about 7.8% share.

OLED TVs, which are continuously increasing in demand worldwide compared to the Smartphone market, are expected to be in short supply this year. LG Display, the only OLED TV panel supplier, will continue to invest in production for the next five years. With the recent approval of new production facility for OLED TV panel in Guangzhou, the full-scale equipment move-in is expected this year. In Paju P10 investment plan, it was confirmed that LG Display will invest in OLED TV panel production line instead of LCD line investment which was examined before. Thus, the OLED TV market is projected to grow to US $ 5.6 billion. 

LG Display “Strategic direction is OLED. Uncompetitive LCD lines are planned to be switched.”

In the 2Q earnings release conference call hosted on the 25th July, Kim Sang-don, LG Display CFO, said, “Looking back at the first half of 2018, the market was in a difficult situation due to the slump in prices, the traditional off-peak season and increased display supply from China. We expected the market conditions to be stabilized in the first half of this year from the bad market condition of the second half of last year, but it has continued to decline more rapidly and steeply. However, with starting the second half of 2018, it has been observing that the price is rising since July owing to upcoming favorable seasonality and customer restocking.”

“Although the market situation has changed favorably in the second half of the year, it is different from the past supply and demand cycle because of the uncertainty of forecasts. Moreover, the oversupply and asymmetric competition in the display market are unavoidable.” LG Display announced that it will maintain its conservative strategy in the second half of the year as the unpredictability is still high.

LG Display’s sales revenue in the second quarter of 2018 was KRW 5,611 billion, decreased by 15% compared to the second quarter of 2017. Operating loss in the second quarter of 2018 recorded KRW 228 billion. This compares with the operating loss of KRW 98 billion in the first quarter of 2018 and the operating profit of KRW 804 billion in the second quarter of 2017. The company suffered a large deficit due to a continued and steep decline in panel prices and lower demand in panels following the previous quarter. Although the shipment was increased by 2% QoQ, the selling price per area (m2) was decreased by 4%.

As a positive indicator, the TV panel price fell sharply, but the overall panel price decline was only 1% due to the competitive position of OLED panels. The market is anticipated to turn into positive situation in the third quarter, compared to the first half of the year, since panel shipments are expected to increase with the orders to restock the inventory.

LG Display, which is currently conducting both LCD and OLED business with small and medium sized panels and large area panels, mentioned clearly about its future strategic direction including the direction for the second half of the year as “concentrating on OLED business and focusing on high value of LCD business” in this conference call.

LG Display announced that it will focus more on differentiated LCD features and technologies in the IT sector such as narrow bezel, IPS borderless, and oxide technology, as well as high-value-added products such as larger-size TV panels and commercial displays, considering that a structural oversupply in panels and fierce competition among display makers are expected to continue down the road.

In addition, LG Display will achieve a turnaround to profit in the OLED TV sector in the third quarter of 2018. By making its final decision to invest in its Gen 10.5 OLED panel production line in Paju, Korea, and by starting mass production in the latter half of 2019 at its Gen 8.5 OLED production line now under construction in Guangzhou, China, LG Display will accelerate the expansion of the global large-size OLED market. Furthermore, additional production facilities for OLED 8.5 generation are known to be considered with the plan that the rationalization of LCDs during the year is also to be implemented although there was no direct mention of the timing and specific lines. For the plastic small and medium-sized OLED panel business, which is experiencing difficult times, compared to large area OLED, for which LG is expanding the production capacity in response to increasing demand, it said that they are preparing for future markets with the necessary strategic technologies with the emphasis of mobile and automotive markets. The E6-1 line, which has been mentioned as a production plant for Apple, is expected to begin mass production in the fourth quarter of this year, revealing the possibility of a possible supply of display to the iPhone OLED model in 2018. In addition, demand for OLED panels is increasing in the automobile market, and it is expected that full-scale business will start in the second half of next year. At the current order backlog, it is confirmed that OLED panels are in the late stage of about 10%. This means that much of the work has already been done. Finally, LG Display is well aware of the lack of funding and funding shortfalls over its competitors in relation to its future preparations. The company plans to reduce its capex by about 3trillion won by 2020, with a substantial portion of depreciation and amortization It is possible through internal working capital management and it plans to borrow the rest. LG Display confirmed that it has not reviewed the rights issue several times in the market, and LG Display has thoroughly prepared a variety of OLED portfolios, revealing its commitment to success by differentiating it from its competitors in the area of latecomers.

TV용 8세대 QD-OLED 투자 비용 얼마나 될까?

유비리서치에서 최근 발간한 “2018 OLED 장비 보고서”에서 삼성디스플레이가 개발을 시작한 QD-OLED 투자 비용이 얼마나 필요한지를 분석하였다.

삼성디스플레이가 추구하고 있는 QD-OLED는 청색 OLED에서 나오는 빛을 QD(quantum dot) 재료를 통하여 녹색과 적색을 분리하여 RGB 3색을 나타내는 방식이다. QD 재료를 통과한 빛은 다시한번 칼라 필터를 통과하며 보다 풍부한 색감을 나타내게 된다.

QD-OLED는 LG디스플레이가 제조하고 있는 WRGB OLED와 제조 방식과 유사한 부분이 매우 많다. 우선 TFT는 양사 모두 oxide TFT를 사용하고 있다. WRGB OLED는 청색이 두 번 도포되며 그 사이에 적색과 녹색이 증착 된다. 이에 비해 QD-OLED는 청색 재료만 두 번 증착하여 제작된다. 두 방식 모두 증착용 마스크는 가운데가 비어 있는 오픈 마스크를 사용한다.

QD-OLED와 WRGB OLED의 칼라필터 제조 비용을 동일할 것으로 추정되나 QD-OLED는 QD 재료를 코팅하는 장비가 추가로 도입되어야 한다.

보고서에 의하면 모듈과 cell, encapsulation, 증착기는 유사한 장비가 사용될 수 있어 투자 비용 역시 대등할 것으로 예상된다. 하지만 WRGB OLED는 bottom emission 방식이어서 TFT를 포함한 backplane 제조시에 같이 형성되나 QD-OLED는 top emission 방식을 추구하고 있어 상판 유리 기판에 칼라필터를 별도로 제작하고, 그 위에 다시 QD층을 패터닝하여 만든다. 따라서 QD-OLED는 WRGB OLED에 비해 다소 높은 투자 비용이 필요해진다.

8세대 26K 기준으로 투자비를 계산하였을 때 QD-OLED는 1.1 billion$로서 WRGB OLED 1.07 billion$에 비해 1.03배 높을 것으로 예상된다. 이에 비해 JOLED에서 사업화를 추진중인 잉크젯 방식의 OLED 제조에 필요한 투자 금액은 0.88 billion$로서 QD-OLED의 80% 수준이 될 것으로 본 보고서는 기술하고 있다.

‘18년 2분기 AMOLED Display Market Tracks’ 발간

유비리서치는 최근 2018년 2분기 시장 업데이트를 포함하는 “2Q 18 AMOLED Display Market Tracks”를 발간하였다. 이번에 발간한 내용은 OLED 디스플레이 패널 업체들의 투자 현황과 2018년부터 2022년까지의 OLED 디스플레이 시장전망, OLED 수요와 공급 트렌드, 그리고 삼성디스플레이와 전세계 OLED 디스플레이 패널 업체들과의 OLED 스마트폰 사업에 대한 경쟁력 분석을 포함하고 있다.

엑셀 스프레드시트에 Data의 형태로 발간된 시장 업데이트는 전세계 15개의 OLED 디스플레이 패널 업체들의 생산 라인 현황과 향후 투자를 통해 추가되는 라인 현황과 스마트폰, TV등 주요 OLED 어플리케이션 시장과 국가별 시장 전망 등을 주요 내용으로 다루고 있다.

삼성전자의 갤럭시S 시리즈와 Apple의 iPhone이 대부분의 시장을 점유하고 있는 프리미엄 스마트폰 시장이 예상치를 밑도는 실적으로 인해 2018년 1분기 전체 OLED 모바일 세트(스마트폰, 스마트 와치 등 포함) 시장의 수요는 작년 4분기 130백만대에서 98백만대로 감소했다. OLED 모바일 세트 시장은 Apple의 신규 스마트폰 모델이 출시되는 3분기까지 서서히 수요를 회복하여 2018년 말 경에는 작년 같은 시기 수요를 회복할 전망이다. 또한 삼성디스플레이가 중국시장에서 LCD와의 경쟁을 위해 모바일 용 Rigid OLED 패널의 가격을 약 25불 수준으로 낮춰 경쟁력을 확보함에 따라 하반기 스마트폰 시장의 회복에 긍정적인 영향을 줄 것으로 기대된다.

 

 

과거에 비해 신규 모델의 혁신적인 변화가 없는 등의 이유로 소비자들의 스마트폰 교체 주기가 길어지고 인도와 남미, 아프리카 등 제3세계 국가들을 제외한 대부분의 지역에서의 스마트폰 보급률이 거의 한계점에 다다라 최근 스마트폰 시장의 침체에 대한 전망이 대부분이다. 시장의 반등을 위해서 이전과는 다른 폼 팩터(Form factor)를 적용하기 위한 기술과 디자인에 대한 관심이 높아지고 있다. 이와 관련하여 올해 말 혹은 내년 초 출시를 예상하고 있는 삼성전자의 Foldable OLED 스마트폰을 놓고 기존의 엣지 형태의 플렉서블 디스플레이에서 (Static Flexible Display) 접는 형태의 플렉서블 디스플레이가 (Dynamic Flexible Display)가 새로운 스마트폰의 형태로서 성공할 것인가에 대해 관심이 집중되고 있다.

 

유비리서치는 2018년 4.3억만대의 OLED 스마트폰 시장이 2022년 약 2배의 9억대 수준으로 성장, Foldable OLED 스마트폰 시장은 2019년 약 1백만대에서 2022년 18백만대까지 성장할 것으로 기대하고 있다. 이는 LG디스플레이와 BOE등 삼성디스플레이 외 패널업체들의 OLED 패널 양산 라인 확대를 반영한 것으로 향후 신규 어플리케이션의 개발과 스마트폰 시장의 움직임에 따라 업데이트 할 예정이다.

OLED 패널 시장은 여전히 스마트폰 용 OLED 패널이 전체 시장의 91%를 점유하고 있으며 업체를 기준으로는 삼성디스플레이가 전체 OLED 패널 시장 실적의 90%를, LG 디스플레이가 뒤를 이어 약 7.8%를 차지하고 있는 것으로 나타났다.

스마트폰 시장에 비해 전세계 적으로 꾸준히 수요가 증가하고 있는 OLED TV는 올해도 수요에 비해 공급이 부족할 것으로 분석되며 유일한 OLED TV용 패널 공급업체인 LG디스플레이는 향후 5년간 생산확대를 위해 지속적인 투자를 진행할 예정이다. 최근 광저우 OLED TV 패널용 생산 공장의 승인으로 본격적으로 설비 반입 등이 진행될 예정이며 파주 P10 투자계획에도 지난해 LCD 생산라인 투자 검토에서 OLED TV용 패널 생산라인 투자를 진행하고 있는 것으로 확인됨에 따라 OLED TV 시장은 2022년 5,6 B달러 규모로 성장할 전망이다.

 

TV向け第8世代QD-OLEDへの投資額は?

最近、UBI Researchが発行した『AMOLED製造・検査装置産業レポート』では、Samsung Displayが開発を始めたQD-OLEDへの投資額がどれくらいなのかを分析した。

Samsung Displayが目指しているQD-OLEDは、青色OLEDから放出される光が量子ドット(Quantum Dot、QD)材料を通って緑色と赤色に分離され、RGBの3色を実現する方式で製造される。QD材料を通り抜けた光は、再びカラーフィルターを通り、さらに豊かな色を表現できるようになる。

このようなQD-OLEDの製造方式は、LG DisplayのWRGB OLEDと似ている部分が多い。まず、TFTは2社ともにOxide TFTを使用している。WRGB OLEDは青色が2回塗布され、その間に赤色と緑色が蒸着される。それに比べ、QD-OLEDは青色材料のみ2回蒸着して製造される。蒸着用マスクは、両方ともオープンマスク(Open Mask)を使用する。

 

 

QD-OLEDとWRGB OLEDのカラーフィルターの製造費は同様であると考えられるが、QD-OLEDの場合、QD材料をコーティングする装置を追加導入しなければならない。

本レポートによると、モジュールとセル、封止、蒸着装置は、同じ装置が使用される可能性があり、投資額もほぼ同様になると予想される。しかし、WRGB OLEDは背面発光方式のため、TFTを含めたバックプレーンを製造する際に同時に形成される反面、QD-OLEDは前面発光方式のため、上部のガラス基板にカラーフィルターを個別に形成し、その上に再度QD層をパターニングして製造する。その結果、QD-OLEDにはWRGB OLEDより高い投資額が必要となる。

第8世代の26Kを基準に投資額を計算してみると、QD-OLEDは11億米ドルで、10億7,000万米ドルのWRGB OLEDに比べて1.03倍高くなることが見込まれる。一方、JOLEDが事業化を進めている印刷方式OLEDの製造に必要な投資額は8億8,000万米ドルで、QD-OLEDの80%程度になるとみられる。

Foldable OLEDの核心、カバーウィンドウの競争激化

<KOLON Industries(左)とSKC(右)の透明PIフィルム、参考:KOLON Industries>

 

Foldable OLEDの量産が今年末に開始されると期待される中で、Foldable OLEDの主要材料の一つであるカバーウィンドウの競争が激しくなる見込みだ。Foldable OLEDはディスプレイが折りたたれる特性から、従来のカバーウィンドウに使用されていたガラスは割れるため、続けて使用することができない。

従って、割れないカバーウィンドウとして透明PIと薄板ガラスの開発が、積極的に進められている。特に透明PIフィルムに関しては、Sumitomo Chemicalと韓国のKOLON IndustriesやSKCの競争が予想される。Sumitomo Chemicalは、Samsung Electronicsが来年発売予定のFoldableスマートフォンに採用されるFoldable OLEDカバーウィンドウ向け透明PIフィルムを供給する最初のメーカーになるという。

しかし、透明PIフィルムのカバーウィンドウは、ガラスのカバーウィンドウの硬度と外観特性を満たせないため、改善が必要な状況にある。Samsung DisplayはSumitomo Chemicalの透明PIフィルムの他にも、多くのメーカーの透明PIフィルムを検討している。

Sumitomo Chemicalの透明PIフィルムと激しく競い合っているメーカーは、韓国のKOLON IndustriesとSKCである。KOLON Industriesは約10余年前から透明PIフィルムを開発しており、現在唯一透明PIフィルム量産設備を備えているメーカーである。SKCもフィルムの製造技術力を基に、2017年末に透明PIフィルムの設備投資を行った。

他に、薄板ガラスをFoldable OLED用カバーウィンドウとして開発する動きも出ている。主要メーカーにはAsahi GlassとドイツのSCHOTTがあり、厚さ0.1mm以下の実現に向けて開発を進めている。しかし、薄板ガラスも折りたたまれた状態では、耐久性に問題があると知られている。

Foldableスマートフォンの発売時期が迫ってきている中、OLEDパネルメーカーとカバーウィンドウ材料メーカーがどのような材料と構造、特性のFoldable OLED用カバーウィンドウを採用するかに業界の関心が集まっている。

Material Science、中国最大のOLED製造メーカーに赤色プライム層材料を量産供給

OLED材料メーカーのMaterial Scienceは、来月の8月から赤色プライム層材料を中国最大のOLED製造メーカーに、量産供給することを16日明らかにした。

赤色プライム層材料は、赤色を発する発光層(EML)と正孔輸送層(HTL)の間に蒸着され、発光効率を高める材料である。陰極から出た電子がEMLを過ぎてHTLまで侵入しないように防ぐことで、OLED発光効率を高くするため、OLED機器の使用時間を増やすことができる。

Material Scienceが開発した赤色プライム層材料は、2016年に中国LTOPTOと設立した合弁会社LTMSで生産して供給する予定だ。合弁パートナーのLTOPTOは、LCD用液晶とOLED原料などを生産する化学会社である。

LTMSは昨年の2017年上半期に、中国陝西省西安に量産設備を構築し、今回の契約によって8月から稼働を開始する。LTMSは現在、月産500㎏規模の生産設備を備えているが、今後、中国内のOLEDメーカーと追加供給の契約が締結されれば、月産1tまで生産設備を拡大する予定だ。月500㎏という生産能力は、第6世代OLEDの生産ライン6本(マザーガラス投入基準で月9万枚)に供給できる規模である。

UBI Researchが発行した『AMOLED Emitting Material Market Track_1Q18』によると、赤色プライム層材料市場は、2018年から2022年まで年平均成長率35%を記録し、2022年には2億4,800万米ドル規模になるとみられる。

언브레이커블 OLED, OLED 시장의 새로운 다크호스가 될 수 있을까?

삼성디스플레이에서 언브레이커블 OLED panel을 공개하여 주목받고 있다.

삼성디스플레이는 깨지지 않는 스마트폰용 패널을 개발해, 美 산업안전보건청 공인 시험기관인 UL(美 보험협회시험소, Underwriters Laboratories Inc.)로부터 인증을 받았다고 23일 밝혔다.

 

<삼성디스플레이의 언브레이커블 OLED, 삼성디스플레이>

 

삼성디스플레이는 플렉시블 OLED 패널에 플라스틱 소재의 커버 윈도우를 부착해, 기판과 윈도우 모두 깨지지 않는 완벽한 언브레이커블(Unbreakable) 패널을 완성했다.

현재 상용화된 플렉시블 디스플레이는 깨지지 않는 플라스틱 기판을 사용하지만, 유리 소재의 커버 윈도우를 부착해 강한 충격을 받을 경우 윈도우가 깨지는 문제가 발생한다.

UL에 따르면 삼성디스플레이가 개발한 언브레이커블 디스플레이는 美 국방부 군사 표준규격(US Military Standard)에 맞춰 실시한 내구성 테스트를 완벽하게 통과했다. 1.2미터 높이에서 26회 실시한 낙하 테스트에서 제품의 전면부, 측면부, 모서리 부분 모두 파손 없이 정상적으로 작동했으며, 극한의 저온(-32)/고온(71) 테스트에서도 문제 없이 작동했다.

특히 美 국방부 군사 표준규격보다 더 높은 1.8미터 높이에서 실시한 낙하 테스트에서도 삼성디스플레이의 언브레이커블 패널은 손상 없이 정상적으로 작동했다.

삼성디스플레이 관계자는최근 개발되고 있는 플라스틱 윈도우는 깨지지 않는 내구성에 유리와 흡사한 투과율과 경도를 갖추고 무게까지 가벼워 휴대용 전자기기에 특히 적합하다앞으로 언브레이커블 패널이 스마트폰은 물론 안전기준이 까다로운 차량용 디스플레이나 군사용 모바일 기기, 학습용 태블릿PC, 휴대용 게임기 등 다양한 전자제품에 활용될 것으로 기대하고 있다고 밝혔다.

삼성관계자의 말처럼 언브레이커블 OLED가 적용될 수 있는 분야는 다양할 것으로 기대되고 있다. 하지만 커버윈도우가 glass가 아닌 film인 만큼 이미 유리에 시각과 촉각이 적응 되어있는 소비자들에게 어떤 반응을 얻을지가 관건이다. 또한 스마트폰의 경우 2~3년 간격으로 주로 교체되고 있고 커버가 깨졌을 시 디스플레이를 교체해주는 등의 교체수요도 중요하다. 하지만 언브레이커블 OLED가 상용화가 된다면 이러한 교체수요는 감소될 수 있지만 다른 한편으로는 깨지지 않는 다는점이 소비자들의 구매욕을 끄는 큰 마케팅 포인트가 될 수 있다.

언브레이커블 OLED가 적용된 제품들이 실제 시장에서 얼마만큼의 성과를 거둘 수 있을지 향후 set 업체와 display업체들의 움직임이 기대된다.

LG Display “전략적 방향은 OLED, 점차적으로 경쟁력 없는 LCD 라인 전환 계획”

김상돈 LG Display CFO는 25일에 주최한 컨퍼런스 콜에서 “2018년 상반기를 돌아보면 전통적인 비수기 시즌과 중국 발 디스플레이 공급 증가로 인해 판가 하락으로 어려운 시장 상황이었다. 작년 하반기부터 좋지 않던 시장 상황이 올해 상반기 안정될 것으로 예상하였으나 오히려 더 빠르고 가파르게 하락하였다.”고 말했다. 하지만, 2018년 하반기는 계절적 특수성과 고객의 재고 확충 맞물려 7월부터 가격이 상승하는 모습을 보이고 있다고 밝혔다. .

하반기에 진입하여 시장의 상황이 우호적으로 변경되고 있으나 예측 불확실성으로 과거 시장과는 차이가 있으며 더욱이 앞으로 디스플레이 시장의 공급과잉이랑 비대칭 경쟁 구도는 불가피한 상황임을 전했다. 이에 대해, 시장의 변동성 확대가 예상 됨에 따라 LG Display는 하반기에도 보수적인 전략을 유지할 것임을 밝혔다.

LG Display의 2018년 2분기 매출은 5조6112억원, 영업손실은 2281억원을 기록했다. 전년 동기 대비 매출은 15% 감소했고 영업이익은 8040억원에서 지난 분기에 이어 패널 출하의 예상 대비 하회 등의 어려운 시장 상황을 반영하여 계속적으로 큰 폭 적자를 면하지 못하였다. 출하 면적은 전분기 대비 2% 증가 하였지만 면적(m2)당 판가는 4% 감소하였다.

긍정적인 지표로는 TV 패널 판가 하락이 컸으나 OLED 패널의 경쟁력 우위 포지션으로 인해 전채 패널 판가 하락은 1%에 그쳤다. 3분기에는 면적 기준 출하 큰 폭으로 증가, 업계의 재고 보충을 위해 주문 증가 예상 등 상반기 대비 시장상황이 긍정적일 것으로 보고 있다.

현재 LCD와 OLED 중소형과 대형 패널 사업 모두를 하고 있는 LG Display는 이번 컨퍼런스콜을 통해 “OLED 사업에 집중, LCD 사업은 고부가 가치에 집중” 이라는 하반기와 향후 LG Display의 전략적 방향에 대해 명확히 언급하였다.

현재 IT 산업이 역 장하고 있어 LCD 산업이 어렵지만, 좁은 베젤(Narrow Bezel) 혹은 베젤의 삭제(Borderless)등 차별화 기술을 통해 하이엔드 부분과 초대형 커머셜 고부가 가치 제품을 중심으로 사업을 진행할 것임을 전달했다.

OLED는 LG Display가 향후 현재 산업 1위 자리를 유지하고 성장하기위해 중요한 사업으로 3분기중 OLED TV는 흑자 전환을 예상하고 있으며 최근 승인이 확정된 중국 광저우의 생산라인과 파주 P10공장의 10.5세대 OLED 생산라인 투자를 앞당겨 OLED 대형 시장을 드라이브 할 것이라는 입장이다. 또한 직접적으로 시기와 특정 라인에 대한 언급은 없었지만 연내 LCD 합리화 계획을 진행하여 OLED 8.5세대 추가 생산 공장 증설 계획도 내비쳤다.

증가하는 수요에 대응해 생산 규모를 늘리고 있는 대형 OLED 사업에 비해, 힘든 시기를 겪고 있는 플라스틱 중소형 OLED 패널 사업에 대해서는 모바일과 자동차 시장을 강조하며 필요한 전략 기술로 미래 시장에 대한 준비를 진행하고 있음을 전달했다.

Apple향 생산공장으로 거론되어온 E6-1라인은 올해 4분기 양산을 시작할 것으로 언급한 것을 미루어 최근 2018년 iPhone OLED 모델에 디스플레이 공급과 관련한 사실 가능성을 짐작할 수 있는 것으로 드러났다. 또한 자동차 시장에서도 OLED 패널의 수요가 증가하고 있으며 내년 하반기 본격적인 비즈니스가 시작될 전망임을 밝혔으며 현재 수주 잔고에서 OLED 패널은 약 10% 후반 수준으로 이미 상당 부분 진행되고 있음을 확인 하였다.

마지막으로, LG Display의 미래 준비와 관련하여 경쟁사 대비 예산 부족과 펀딩 부족의 우려를 잘 알고 있으며 2020년까지 기존에 계획한 Capex에서 약 3조원 줄인 수준으로 진행할 계획이며 이 중 상당부분은 감가상각비와 내부 운전자본관리를 통해 가능하며 나머지는 차입할 계획임을 밝혔다. 시장에서 몇차례 언급된 유상증자는 검토하고 있지 않음을 확인하였으며 LG Display는 OLED의 다양한 포트폴리오를 철저히 준비하여 후발주자인 분야에서도 경쟁기업 대비 차별화를 통한 사업 성공의 의지를 밝혔다.

Material Science、中国最大のOLED製造メーカーに赤色プライム層材料を量産供給

OLED材料メーカーのMaterial Scienceは、来月の8月から赤色プライム層材料を中国最大のOLED製造メーカーに、量産供給することを16日明らかにした。

赤色プライム層材料は、赤色を発する発光層(EML)と正孔輸送層(HTL)の間に蒸着され、発光効率を高める材料である。陰極から出た電子がEMLを過ぎてHTLまで侵入しないように防ぐことで、OLED発光効率を高くするため、OLED機器の使用時間を増やすことができる。

 

Material Scienceが開発した赤色プライム層材料は、2016年に中国LTOPTOと設立した合弁会社LTMSで生産して供給する予定だ。合弁パートナーのLTOPTOは、LCD用液晶とOLED原料などを生産する化学会社である。

 

LTMSは昨年の2017年上半期に、中国陝西省西安に量産設備を構築し、今回の契約によって8月から稼働を開始する。LTMSは現在、月産500㎏規模の生産設備を備えているが、今後、中国内のOLEDメーカーと追加供給の契約が締結されれば、月産1tまで生産設備を拡大する予定だ。月500㎏という生産能力は、第6世代OLEDの生産ライン6本(マザーガラス投入基準で月9万枚)に供給できる規模である。

 

UBI Researchが発行した『AMOLED Emitting Material Market Track_1Q18』によると、赤色プライム層材料市場は、2018年から2022年まで年平均成長率35%を記録し、2022年には2億4,800万米ドル規模になるとみられる。

LG Display의 대면적 OLED 사업 집중, 발광재료 업체들의 실적 개선 이끌까

LG Display725일에 진행한 20182분기 실적발표에서 파주 10.5세대 공장(P10)에서 대면적 LCD가 아닌 대면적 OLED를 우선 생산키로 한 방침을 확정했다.

LG Display는 이날 대형 OLED 사업이 안정화를 띔에 따라 생산에 속도를 올려 실적 부진을 만회하겠다는 전략을 밝혔다. 김상돈 LG Display CFO내년 400만대, 2020 700만대, 2021 1000만대 판매 목표를 가지고 있다고 언급하며, 중국 광저우 8.5세대 공장이 내년 하반기 가동을 시작하고 LCD 공장까지 OLED 공장으로 전환하면 OLED TV 패널 생산량이 빠르게 증가할 것으로 기대했다.

대면적 LCD 대신 대면적 OLED로의 사업 집중에 따라, 대면적 OLED와 관련된 발광재료 업체들의 실적 개선도 기대된다. 현재 LG Display의 대면적 OLED용 재료를 공급하는 업체로는 MerckNoveled, LG Chemical, Heesung Material, Idemitsu Kosan 등이 있다.

이 중 LG Chemical은 인광 레드 호스트와 형광 블루 호스트, HIL, ETL, CPL을 공급하고 있으며 Heesung MaterialCGLCPL을 공급하고 있다.

한편, 유비리서치가 발간한 ‘2018 AMOLED Emitting Material Market Track 1Q18’에서는 대면적 OLED의 재료 사용 비용이 2018년에 US$ 279 million에서 연평균 25%씩 증가하여 2022년에는 US$ 692 million이 될 것으로 전망했다. LG Display의 대면적 OLED 사업 집중에 따라 재료 사용 비용은 더 늘어날 것으로 예상된다.

FlexiGO, developed the durability test equipment capable of accurate evaluation for foldable materials

With the recent announcement that Samsung Electronics and Huawei are aiming to launch smart phones with foldable OLED, folder-type smartphones are drawing attention.

 Display companies are converting glass materials used in the existing substrates and cover windows into plastic materials. Consequently, the durability of plastic materials is becoming an important issue.

There are various types of durability tests, but the most typical durability inspection is the folding test. The folding test is an experiment that repeatedly bends and unfolds the foldable materials including plastic. Typically, a mechanical device is used for pivoting the rotating plate after fixing some part of the foldable material to the fixed plate and fixing the other remaining part to the rotating plate. However, in the conventional devices, the axis of foldable material is different with that of the rotating plate, the foldable material moves along the rotation path of the rotating plate, not the original rotation path of the material. Thus, there is a possibility that a tensile force acts on the folder material. To solve this problem, FlexiGO recently developed Foldy series, new durability test equipment to test foldable materials.

<FlexiGO’s folding test equipment, Source: flexigo.co.kr>

In addition to the conventional fixed plate and rotating plate, the Foldy series adds a motion controller that supports the fixed plate to move forward and backward for the foldable to be moved only through the original rotation path, so that no other stress is applied to the material. As a sliding device is mounted on the motion controller, the fixed plate moves forward and backward, and the rotating plate performs a rotary motion so that the foldable material can slide on the rotating plate.

The Foldy series includes micro vision, surface profiling, and colorimeter. Foldy-10 and Foldy-100 products can be adopted for the durability test in different test environments. In addition, it is possible to mount an additional inspection system, so it is expected that the accurate durability test of various accurate foldable materials is to be possible.

8K OLED TV、下半期には見られるのか?

 

プレミアムTV市場の競争がさらに激しくなる見込みだ。SonyのOLED TV市場参入とLG Electronicsの攻撃的な価格下げによって、プレミアムTV市場でOLED TVのシェアは拡大している。しかし、LCD陣営では8Kの高解像度戦略で対応しており、プレミアムTV市場に広がるOLEDの勢いを止めることができるのかに注目が集まっている。

 

Sharpは既に昨年から8K LCD TVを世界で初めて販売し、Samsung Electronicsも今年始めのCESで8K TVを展示したことに続き、下半期には8K QLED(QD-LCD)製品を発売する予定だ。OLED陣営では、LG DisplayがCESで88型8K OLED TVを展示したが、8K OLED TVを下半期に発売できるのかはまだ分からない。

 

現在、量産が進んでいるOLED TVは、背面発光(Bottom emission)構造で、TFTを通して採光するため、ピクセルでTFTを除いた部分から光が放出される方式だ。そのため、同じサイズのTVでも、解像度が高くなるほどピクセルサイズは小さくなるものの、TFTサイズの減少には制約があるため、光が放出される範囲がさらに狭くなる。同じサイズで高解像度を実現するためには、開口率を最大限に高めるか、または発光材料の性能を改善する必要がある。

 

開口率を向上させる方法には、前面発光(Top emission)構造の採用がある。前面発光構造は、光がTFT方向ではなく、封止方向に放出されるため、背面発光構造より高い開口率を確保することができる。しかし、現在、不透明なメタルシートの封止を、透明な材料に変えなければならないことや、カラーフィルターを封止の上側に形成するために、工程を変更しなけらばならないという問題が生じる。

 

発光材料に関しては、青色TADFや新しい青色材料の開発が積極的に行われている。LG Displayが公開した88型8K OLED TVには、背面発光構造が採用されているため、画面密度が約100 ppiとなり、現在販売されている55型4Kの80 ppiより20%高い。単純にディスプレイ全体のサイズとピクセルサイズを比較してみると、55型4Kのピクセルが88型8Kのピクセルより約40%ほど大きいという計算ができる。

 

つまり、55型4Kと同レベルの輝度と寿命を確保するためには、TFTの設計を最適化し、発光材料の性能を向上させ、40%小さくなるピクセルサイズをカバーしなければならない。

 

果たして8K OLED TVはこのような問題を全て解決し、今年の下半期に本格的な発売開始が予想される8K LCD TVに立ち向かい、無事に発売できるのか、業界の関心が寄せられている。

8K OLED TV, Can we see it in the second half of the year?

 

Competition in the premium TV market is expected to be cutthroat.

The market share of OLED TV is on the rise in the premium TV market due to Sony’s entry into the OLED TV market and LG Electronics’ aggressive price cuts. However, LCD camp is responding with 8K high-resolution strategy, and attention is focused on whether it can prevent the rise of OLED in the premium TV market.

Sharp has already started selling 8K LCD TVs for the first time in the world since last year. Samsung Electronics showcased 8K TV at CES earlier this year, and will launch 8 K QLED (QD-LCD) products in the second half of the year. In the OLED camp, LG Display exhibited 88inch 8K OLED TV at CES, but the launch of 8K OLED TV in the second half is still unknown.

OLED TVs, which are currently in mass production, are based on bottom emission type. Thus, the light is emitted from the remaining portion of the pixel except the TFT region since the light is emitted through the TFT. Therefore, in the same size TV, as the resolution increases, the pixel size becomes smaller, but the area where the size of the TFT is reduced is limited, so that the area where the light is emitted becomes narrower. Consequently, in order to realize a high resolution at the same size, it is necessary to broaden the aperture ratio as much as possible or improve the performance of the emitting materials.

 

As a way of increasing the aperture ratio, there is a method of applying a top emission structure. Since the top emission structure emits light in the encapsulation direction, not the TFT direction, it can secure a wider aperture ratio than the bottom emission. However, there are pending problems that the encapsulation using opaque metal sheet should be changed to a transparent material and the color filter should be formed above the encapsulation with the change of the process.

The development of TADF blue and new blue materials is actively underway in the emitting material side.

The 88inch 8K OLED TV released by LG Display is made with a bottom emission structure and its ppi is about 100, which is about 20% higher than 80 ppi of the 55inch 4K currently being sold. When the pixel size is compared with the whole display size, the 55 inch 4K pixel is calculated to be about 40% wider than the 88inch 8k pixel.

In order to achieve the same level of brightness and lifetime as 55inch 4K, it is necessary to optimize the TFT design and improve the performance of the emitting materials to make up for the 40% decrease in pixel size. The industry is paying attention to whether the 8K OLED TV will be launched, with resolving above-mentioned issues, against the 8K LCD TV, which is expected to be released in the second half of the year.

FlexiGO, 폴더블 소재의 정확한 내구성 평가가 가능한 폴딩 장치 개발

최근 Samsung Electronic와 Huawei가 폴더블 OLED가 탑재된 스마트폰 출시를 목표로 하고 있는 것이 알려지면서 폴더블 스마트폰이 주목받고 있다.

디스플레이 업체에서는 기존의 기판이나 커버 윈도우에 적용되었던 유리 소재를 플라스틱 소재로 전환하고 있으며, 이에 따라 플라스틱 소재의 내구성이 중요한 이슈로 떠오르고 있다.

내구성 시험에는 다양한 종류가 있지만 가장 대표적인 내구성 시험은 폴딩 시험이다. 폴딩 시험은 플라스틱을 포함한 폴더블 소재를 구부리고 펼치는 동작을 반복하는 시험으로서, 대표적으로 폴더블 소재의 일부를 고정판에 고정시키고 나머지는 회동판에 고정시킨 후 회동판을 기계적으로 회동운동 시키는 장치가 사용되고 있다.

그러나 기존의 장치들은 폴더블 소재와 회동판의 축이 서로 달라 회동 운동 시 폴더블 소재가 소재 본연의 회동 경로가 아닌 회동판의 회동 경로를 따라가기 때문에 폴더블 소재에 인장력이 작용할 가능성이 있었다. 이러한 문제를 해결하기 위해, 최근 FlexiGO에서는 폴더블 소재의 폴딩 시험을 위한 새로운 폴딩 장치인 Foldy series를 개발했다.

<FlexiGO의 폴딩 장치, Source: flexigo.co.kr>

 

Foldy series는 기존의 고정판과 회동판 외에 고정판을 진퇴운동 하도록 지지하는 모션 컨트롤러를 추가하여 폴더블 소재가 본연의 회전 경로로만 이동하게끔 유도해 다른 응력이 소재에 가해지지 않도록 하였다. 모션 컨트롤러에 슬라이딩장치가 탑재 되어 고정판은 진퇴운동을 하고 회동판은 회동운동을 하여 폴더블 소재가 회동판에서 슬라이딩 운동을 할 수 있도록 하는 것이 특징이다.

Foldy series에는 micro vision과 surface profiling, colorimeter가 포함되어 있으며, Foldy-10과 Foldy-100 등 제품들에 따라 시험 환경을 달리하여 내구성 평가를 진행할 수 있다. 이 밖에 추가적인 검사 시스템 탑재도 가능하기 때문에 다양하고 정확한 폴더블 소재의 내구성 시험이 가능할 것으로 기대를 모으고 있다.

What is the investment cost for large-area OLED that will lead the premium TV market?

■ Investment cost comparison and analysis for WRGB OLED, solution processed OLED and QD-OLED
■ Total OLED process equipment is expected to form a market of US$ 58.8 billion from 2018 to 2022, and inspection equipment market is estimated as US$ 8.4 billion

In the premium TV market, the market share of OLED TVs is steadily rising, and the number of OLED TV camps is gradually increasing. OLED TV adopts color filter to WRGB OLED, and currently LG Display only mass produces the OLED panels.

On the other hand, Samsung Display is developing QD-OLED (blue OLED + quantum dot color filter) to compete with WRGB OLED in the premium TV market. Blue OLED is a technology in which the blue light emitted from OLED passes through a quantum dot layer and a color filter to represent red and green colors.

<Expected structure of QD-OLED>

UBI Research analyzed the structure and investment amount of WRGB OLED and QD-OLED, which are the latest issues, in the‘AMOLED Manufacturing and Inspection Equipment Industry Report’ published on June 6. In addition, the investment amount of the solution process OLED, which has got the industry attention due to its possible implementation of real RGB in large-area OLED, is also analyzed and compared.

As a result of analyzing the equipment investment cost based on the 8th generation 26K, the QD-OLED investment cost is 3% higher than WRGB OLED and the investment cost of solution process OLED is 19% less than that of WRGB OLED.

In the QD-OLED investment cost, it is reflected that QD color filter is separately formed and its laminating process is added. For the analysis of solution processed OLED investment cost, color filter is excluded and ink-jet printer is applied instead of deposition equipment.

In addition, the report forecasts the overall OLED equipment market from 2018 to 2022. The total OLED overall equipment market is expected to reach US$ 106.7 billion from 2018 to 2022. The market for process equipment is projected as US$ 58.8 billion and inspection equipment market is to be US$ 8.4 billion.

8K OLED TV, 하반기에 볼 수 있을까?

 

프리미엄 TV시장 경쟁이 더욱 치열해질 전망이다. Sony의 OLED TV 시장 진입과 LG전자의 공격적인 가격 인하로 프리미엄 TV 시장에서 OLED TV의 점유율이 상승곡선을 그리고 있다. 하지만 LCD진영에서는 8K 고해상도 전략으로 대응하고 있는 추세로 프리미엄 TV시장에서 OLED의 상승세를 저지할 수 있을지 관심이 집중되고 있다.

샤프는 이미 지난해부터 8K LCD TV를 세계 최초로 판매하기 시작하였고, 삼성전자도 올 초 CES에서 8K TV를 전시한데 이어 올 하반기 8K QLED(QD-LCD) 제품을 출시할 예정이다. OLED 진영에서는 LG Display가 CES에서 88inch 8K OLED TV를 전시했지만 8K OLED TV의 하반기 출시 여부는 아직 미지수이다.

현재 양산되고 있는 OLED TV는 bottom emission 방식으로 빛이 TFT를 통과해서 나오기 때문에 pixel에서 TFT영역을 제외한 나머지 부분에서 빛이 나오는 방식이다. 따라서 동일 크기의 TV에서 해상도가 높아질수록 pixel size는 작아지지만 TFT의 크기가 작아지는 부분은 제약이 있기 때문에 빛이 나가는 영역이 더 좁아지게 된다. 따라서 동일 사이즈에서 고해상도 구현을 위해서는 개구율을 최대한 넓히거나 발광재료의 성능을 개선해야 된다.

개구율을 넓히는 방법으로는 top emission 구조를 적용하는 방법이 있다. Top emission구조는 빛이 TFT 방향이 아닌 encapsulation 방향으로 나오기 때문에 bottom emission 대비 더 넓은 개구율을 확보할 수 있다. 하지만 현재 불투명한 metal sheet를 사용하는 encapsulation이 투명한 소재로 바뀌어야 되는 점과 color filter가 encapsulation 위쪽으로 형성되어야 하며 공정이 바뀌는 문제가 있다.

발광재료 쪽에서는 TADF blue나 새로운 blue 재료에 대한 개발이 적극적으로 진행되고 있는 중이다.

LG Display에서 공개한 88inch 8K OLED TV는 bottom emission 구조로 만들어 졌으며 약 100 ppi로 현재 판매되고 있는 55inch 4K의 ppi인 80ppi 보다 20% 높은 수치이다. 단순 전체 display size 대비 pixel size를 비교해보면 55 inch 4K의 pixel이 88inch 8k의 pixel보다 약 40% 넓은 것으로 계산된다.

즉 55inch 4K와 동일 수준의 휘도와 수명을 확보하기 위해서는 TFT 설계를 최적화하고 발광재료 성능을 향상시켜 pixel 크기가 40% 감소한 부분을 만회해야 한다.

이러한 문제를 해결하고 하반기에 출시 본격화가 예상되는 8K LCD TV에 맞서 8K OLED TV가 출시 될 수 있을지 업계의 관심이 주목되고 있다.

 

 

Premium TV 시장을 주도할 대면적 OLED의 투자 비용은?

최근 premium TV 시장은 OLED TV의 점유율이 지속적으로 상승하고 있으며 OLED TV 진영도 꾸준히 증가하고 있는 추세다. OLED TV는 WRGB OLED에 color filter를 적용한 구조로써, 현재 LG Display만이 유일하게 OLED panel을 양산하고 있다.

이에 Samsung Display에서는 premium TV 시장에서 WRGB OLED에 대항하기 위해 blue OLED + quantum dot color filter(이하 QD-OLED)를 개발하고 있는 것으로 알려졌다. Blue OLED는 OLED에서 발광 된 청색광이 quantum dot층과 color filter를 통과해 red와 green 색을 나타내는 기술이다.

<QD-OLED 예상 구조>

유비리서치는 지난 6일 발간한 ‘AMOLED Manufacturing and Inspection Equipment Industry Report’에서 최근 이슈가 되고 있는 WRGB OLED와 QD-OLED의 구조와 투자 금액을 분석했다. 뿐만 아니라, 대면적 OLED에서 real RGB를 구현할 수 있어 주목받고 있는 solution process OLED의 투자 금액도 함께 분석하여 비교했다.

8세대 26K 기준으로 장비 신규 투자비를 분석한 결과, QD-OLED 투자비는 WRGB OLED에 비해 3%가 많고 solution process OLED는 WRGB OLED에 비해 19% 적은 것으로 조사되었다.

QD-OLED 투자비에서는 QD color filter가 따로 형성되고 이를 합착하는 공정이 추가된 내용이 반영되었으며, solution process OLED 투자비에서는 color filter가 제거되고 증착 장비 대신 ink-jet printer가 투입된 내용이 반영되었다.

이 밖에 본 보고서에서는 2018년부터 2022년까지 OLED 전체 장비 시장도 예상하였다. 2018년부터 2022년까지 OLED 전체 장비 시장은 US$ 106.7 billion을 형성할 것으로 전망되며, 공정 장비는 그 중 US$ 58.8 billion, 검사 장비는 US$ 8.4 billion의 시장을 형성할 것으로 예상된다.

The second half of 2018 just started, Chinese OLED panel makers are chasing Korea. Where are they?


작성자: 오하나 (Analyst, hanaoh@ubiresearch.com)
The display industry has been in a state of confusion by the recent leaking of OLED display panel production technology into China.

As of 2018, five companies (BOE, Everdisplay, Tianma, Truly, and Visionox) have OLED production lines in China, among which only BOE has a line that can produce OLED displays (“Plastic OLED”) using plastic substrates, applied to the premium smart phones such as Samsung Galaxy and Apple’s iPhone. Other panel makers are building lines to produce plastic OLED displays targeting mass production this year and next year.

Monthly production capacity planned by Chinese panel makers by the end of 2020 is about 250K, which is more than the monthly production capacity of Samsung Display (about 180K). If China produces a similar level of panels through mass production, it is clear that Korea cannot defeat China in terms of production costs. The main application of the 6G plastic OLED display is a smart phone; however, the global Smartphone market has slowed down since 2015, especially in the premium Smartphone market, there seem no new markets. If mass applications such as smartphones are not developed, panel makers that do not have cost competitiveness will be hard to survive due to a large oversupply in the near-term and falling panel prices.

Korea is evaluated to have a considerable technical advantage since the production of plastic OLED displays requires a high level of technology and process know-how for the time. However, the industry expects that Chinese government’s support for the panel makers with the background of capital as part of the “China Manufacturing 2025” strategy, will shorten the technology gap quickly.

Chinese panel makers ahead of their mass production by 2019 are also reported to be more aggressively scouting Korea’s major OLED engineers. There are about 100 Korean OLED engineers in Chengdu (B7) plant that produces plastic OLED display of BOE. GVO is also known to have recently hired some important OLED engineers with high salaries. CSOT, which has been known to suffer difficulties from the initial research stage, seems to be expediting the construction of mobile OLED production line, employing Korean OLED engineers at major processes from last year. In addition, HKC, which is not a panel maker, is reported to have hired OLED engineers. This is interpreted as a work for investing in the OLED production line of HKC which has only LCD line, and HKC has recently been named as the merger of TIANMA OLED division.
As of 2018, there are no panel makers in China that can produce OLED display panels at the level produced by Korean panel makers. Although the production capacity and sales structure of Chinese panel makers are different from those of Korea, it is difficult to define yields on the same basis. However, the yield of BOE’s Chengdu (B7) plant, known as the mass production line, is still investigated as a single digit. Other panel makers also expect the product quality and yield problems to be difficult to be resolved by the first half of 2019 even if the mass production lines are launched within the year.

In order for the display industry, which contributes significantly to the Korean economy, to maintain its dominant position in the global display industry, it must maintain its competitiveness through various product development, production and sales strategies. Meanwhile, the size of the display industry needs to grow for the growth of the worldwide OLED industry. In order for Chinese panel makers to supply OLED panels with diverse applications, securing the yield might be the key.

The second half of 2018 just started, Chinese OLED panel makers are chasing Korea. Where are they?

Other panel makers are building lines to produce plastic OLED displays targeting mass production this year and next year.

Monthly production capacity planned by Chinese panel makers by the end of 2020 is about 250K, which is more than the monthly production capacity of Samsung Display (about 180K). If China produces a similar level of panels through mass production, it is clear that Korea cannot defeat China in terms of production costs. The main application of the 6G plastic OLED display is a smart phone; however, the global Smartphone market has slowed down since 2015, especially in the premium Smartphone market, there seem no new markets. If mass applications such as smartphones are not developed, panel makers that do not have cost competitiveness will be hard to survive due to a large oversupply in the near-term and falling panel prices.

Korea is evaluated to have a considerable technical advantage since the production of plastic OLED displays requires a high level of technology and process know-how for the time. However, the industry expects that Chinese government’s support for the panel makers with the background of capital as part of the “China Manufacturing 2025” strategy, will shorten the technology gap quickly.

Chinese panel makers ahead of their mass production by 2019 are also reported to be more aggressively scouting Korea’s major OLED engineers. There are about 100 Korean OLED engineers in Chengdu (B7) plant that produces plastic OLED display of BOE. GVO is also known to have recently hired some important OLED engineers with high salaries. CSOT, which has been known to suffer difficulties from the initial research stage, seems to be expediting the construction of mobile OLED production line, employing Korean OLED engineers at major processes from last year. In addition, HKC, which is not a panel maker, is reported to have hired OLED engineers. This is interpreted as a work for investing in the OLED production line of HKC which has only LCD line, and HKC has recently been named as the merger of TIANMA OLED division.
As of 2018, there are no panel makers in China that can produce OLED display panels at the level produced by Korean panel makers. Although the production capacity and sales structure of Chinese panel makers are different from those of Korea, it is difficult to define yields on the same basis. However, the yield of BOE’s Chengdu (B7) plant, known as the mass production line, is still investigated as a single digit. Other panel makers also expect the product quality and yield problems to be difficult to be resolved by the first half of 2019 even if the mass production lines are launched within the year.

In order for the display industry, which contributes significantly to the Korean economy, to maintain its dominant position in the global display industry, it must maintain its competitiveness through various product development, production and sales strategies. Meanwhile, the size of the display industry needs to grow for the growth of the worldwide OLED industry. In order for Chinese panel makers to supply OLED panels with diverse applications, securing the yield might be the key.

2018년 2H 시작, 중국 OLED 패널 업체들의 추격어디까지?

최근 중국으로의 OLED 디스플레이 패널 생산기술 유출 사건과 관련하여 디스플레이 산업이 시끌시끌하다.

2018년 현재, 중국내 OLED 생산라인을 보유하고 있는 업체는 총 5업체로 (BOE, Everdisplay, Tianma, Turly, Visionox) 이중 삼성전자의 Galaxy와 Apple의 iPhone등 프리미엄 스마트폰에 사용되는 플라스틱 기판을 사용하는 OLED 디스플레이(“Plastic OLED”)를 생산할 수 있는 라인을 가지고 있는 곳은 BOE 한 곳에 불과하다. 다른 패널 업체들은 올해와 내년 양산을 타겟으로 Plastic OLED 디스플레이를 생산할 수 있는 라인 건설을 진행하고 있다.

2020년 말까지 중국 패널 업체들이 양산을 계획하고 있는 월 생산 Capa는 약 250K로, 현재 삼성디스플레이의 월 생산 Capa(약 180K)를 넘어서는 수준이다. 중국이 본격적인 양산을 통해 비슷한 수준의 패널을 생산하게 될 경우 생산 원가 측면에서 한국은 중국을 이길 수 없는 구조임은 분명해 보인다. 6세대 Plastic OLED 디스플레이의 주 사용 어플리케이션이 스마트폰인데 전세계 스마트폰 시장은 2015년 이후 성장이 둔화되었으며 특히 프리미엄 스마트폰 시장은 신규시장이 거의 없는 상황이다. 스마트폰과 같은 매스 어플리케이션이 개발되지 않을 경우, 머지 않아 매우 큰 과잉공급과 이는 패널 가격의 하락으로 이어져 원가 경쟁력이 없는 패널 업체는 살아남기 힘들게 될 것이다.

일단은 Plastic OLED 디스플레이 생산은 높은 기술수준과 공정 노하우 등이 필요해 한국이 상당한 기술 우위에 있는 것으로 평가한다. 하지만 산업에서는 “중국제조 2025” 전략의 일환으로 자본을 앞세운 중국 정부의 패널업체 지원이 기술 격차를 빠른 시간안에 단축시킬 것으로 예상하고 있다.

2019년까지 양산을 앞두고 있는 중국 패널 업체들 역시 최근 더욱 적극적으로 한국의 주요 OLED 엔지니어 모셔가기를 하고 있는 것으로 알려지고 있다. BOE의 Plastic OLED 디스플레이를 생산하는 청두(B7) 공장에는 약 100여명에 가까운 한국 OLED 엔지니어가 있는 것으로 알려져 있으며 GVO도 최근 고액 연봉의 중요한 OLED 엔지니어들을 수명 고용한 것으로 파악되고 있다.  초기 연구개발 단계에서부터 어려움을 겪는 것으로 알려져 왔던 CSOT 역시 작년부터 주요 공정의 한국 OLED 엔지니어들을 고용 모바일 OLED 생산 라인 구축에 박차를 가하고 있는 것으로 보여진다. 이밖에 패널업체가 아닌 HKC 역시 OLED 엔지니어들 영입하고 있다고 조사되고 있으며 이는 LCD 라인 밖에 없는 HKC의 OLED 생산 라인 투자를 위한 밑 작업으로 해석되고 있으며 HKC는 최근 티안마 OLED 사업부 합병설에 이름을 올리기도 하였다.

2018년 현재를 기준으로 아직까지는 한국 패널 업체들이 생산하는 수준의 OLED 디스플레이 패널 양산이 가능한 중국의 패널 업체는 없다. 중국 패널 업체들의 생산능력 기준과 판매 구조는 대한민국과 달라 같은 기준으로 수율을 정의 하기는 어렵지만 양산라인이라고 알려져 있는 BOE의 청두(B7)공장의 수율은 여전히 1자리 숫자인 것으로 조사되고 있다. 다른 패널 업체들 역시 올해 안에 양산라인 가동을 한다고 해도 제품 품질과 수율문제는 2019년 상반기까지도 해결이 힘들것으로 예상하고 있다.

한국 경제에 상당부분 일조하는 디스플레이 산업이 지속적으로 전세계 디스플레이 산업에서 우위를 지키기 위해서는 다양한 제품 개발, 생산과 판매 전략을 통해 경쟁력을 유지해야 할 것이다. 또한 전세계 OLED 산업의 성장을 위해 디스플레이 산업의 규모가 커지고 많은 플레이어들이 다양한 어플리케이션에 OLED 패널을 공급하기 위해서는 중국 패널 업체들의 수율 확보가 관건일 것이다.

LCD Smartphone is 4K era, what about OLED Smartphone?

In the past MWC 2017, Sony unveiled the world’s first Smartphone with 4K LCD and it is scheduled to release the Xperia XZ2 Premium with 4K LCD on July 4. Attention is growing whether 4K resolution market is to be launched in earnest in smartphones.

TV market is already moving beyond the 4K to the 8K. Samsung Electronics and Sharp released new TVs with 8K resolution in the first half and Sony plans to release 8K TVs in the second half. LG Display also exhibited 88inch 8K OLED TV at CES 2018. As such, 8K TV is entering the premium TV market, and smart phones are expected to increase the number of products with 4K resolution in response to the higher resolution of TVs.

In the Smartphone, 4K has been implemented in LCD; however, in the case of OLED, QHD resolution is still dominant for the 4 consecutive years.

This is because there are many restrictions on the fine metal mask (FMM) technology that is being applied to OLED manufacturing. The thickness of FMM applied to the current production is about 20 ~ 30um. For 4K fabrication, the thickness should be as thin as 10um, but it is difficult for existing FMM manufacturing method.

As a result, FMM replacement technologies are being developed for high resolution implementation. Typical technologies under developing, include laser FMM patterning with laser, electroforming manufactured by electroplating method, a fine hybrid mask that is used to form a frame by electroplating on a film and pattern the film with a laser, and a surface source that realizes a high resolution by vertically setting the deposition incident angle.

Deposition technologies for high-resolution manufacturing at various exhibitions and conferences are being introduced. Depending on the availability for securing mass production, it is expected to see not only 4K OLED Smartphone, but also high-resolution AR and VR devices of RGB method.

LCD 스마트폰은 4K시대, OLED 스마트폰은?

지난 MWC 2017에서 소니가 세계 최초로 4K LCD를 탑재한 스마트폰을 공개한데 이어 오는 7월 4K LCD가 탑재된 Xperia XZ2 Premium을 출시할 예정으로 스마트폰에서도 4K 해상도 시장이 본격적으로 열릴 것으로 기대되고 있다.

<Sony의 Xperia XZ2 Premium, Source : theverge.com>

이미 TV시장에서는 4K를 넘어서 8K 시장으로 옮겨가고 있는 중이다. 삼성전자와 샤프는 상반기 8K 해상도의 TV 신제품을 공개하였으며, 소니도 8K TV를 하반기 출시 예정이다. LG Display에서도 88inch 8K OLED TV를 CES 2018에서 전시를 하였다. 이처럼 8K TV가 프리미엄 TV 시장에 진입을 하면서 스마트폰도 TV의 고해상도화에 대응하여 4K 해상도를 가진 제품 출시가 증가할 것으로 예상된다.

하지만 스마트폰에서 LCD는 4K를 구현했지만 아직 OLED는 4년째 QHD 해상도에 머물러있는 상황이다.

<삼성전자 갤럭시 시리즈의 해상도 변화, Source : UBI Research DB>

OLED제조에 적용되고 있는 FMM(fine metal mask) 기술에 제약이 많이 있기 때문이다. 현재 양산에 적용되고 있는 FMM의 두께는 약 20~30um 수준이며, 4K 제조를 위해서는 두께가 10um 수준으로 얇아져야 하지만 기존 FMM 제조방식으로는 어려움을 겪고 있는 상황이다.

이에 따라 고해상도 구현을 위한 FMM 대체기술들이 개발되고 있다. 대표적인 기술로는 레이져로 패터닝을 하는 laser FMM과 전주도금방식으로 제조하는 electroforming, 필름에 전주도금으로 프레임을 형성하고 레이져로 film을 패터닝하는 fine hybrid mask, 증착 입사각을 수직으로 하여 고해상도를 구현하는 면소스 등이 개발 중에 있다.

 

각종 전시회와 학회에서 고해상도 제조를 위한 증착기술들이 공개되고 있는 추세이며, 양산성 확보여부에 따라 앞으로 4K OLED 스마트폰, 더 나아가 RGB 방식의 고해상도 AR, VR 기기를 볼 수 있을 전망이다.

How will Samsung Electronics secure its premium TV market share?

Choog Hoon Yi, president of UBI Research, presented about the issues and predictions for 2018 premium TV market at the seminar on the OLED market review in the first half of the year, held by UBI Research on June 28.

He said “The TV demand for 60 inches or more will be expanded from 12 million units in 2016 to 33 million units in 2021 as the investment for Gen10.5 will be increased and therefore the cost for panels will be decreased.

TV prices are expected to decline in 2018 as panel prices fall. In case of Samsung Electronics, TV shipments in the first quarter of 2018 declined 4% YoY to 9.7million units, which led to an operating profit of 4% in its VD division. This is 10% lower than the operating profit of LG Electronics’ HE division.

Lee mentioned ” Samsung Electronics is expected to focus on securing operating profits even if its sales are down. Therefore, they will concentrate on promoting mega-sized products over 65 inches.”

Currently, Samsung plans to use QD-OLED as a TV panel to increase its market share in the premium TV market. QD-OLED is a technology that uses blue OLED as a light source and the light passes through a quantum dot color filter (QDCF) to realize red and green colors.

Lee added that “The success factor of QD-OLED is to be the production of 8K OLED panel of 65 inch or above, but the saturation of premium TV market due to the early investment of LG Display’s 10.5 generation OLED will be a threat.

According to the ‘2018 OLED Emitting Material Industry Report’ published by UBI Research in April, since the QD-OLED is top emission type, the aperture ratio is increased by about 70% compared to the bottom emission, which emits light in the TFT direction. Thus, it is more advantageous to implement 8K resolution and high luminance than the existing WRGB OLED. In addition, it is expected that it will be possible to reach BT.2020, UHD color standard, by using QD material with high color recall rate as color filter.

Meanwhile, UBI Research predicted that OLED TV sales would grow by about 30% annually to about US$ 5.7 billion in 2022.

삼성전자가 프리미엄 TV 시장 점유율을 확보하기 위해서는?

지난 28일 유비리서치가 개최한 ‘상반기 OLED 시장 결산 세미나’에서 이충훈 대표는 2018 프리미엄 TV 시장 이슈와 전망을 발표하였다.

이충훈 대표는 60 inch 이상의 TV수요에 대해 ’2016년 1200만대에서 2021년 3300만대까지 확대될 것’이며, ‘이는 Gen10.5의 투자가 증가함에 따라 패널의 가격이 하락하기 때문이다’고 설명했다.

2018년은 패널 가격이 하락하면서 TV가격도 하락할 전망이다. 삼성전자의 경우 2018년 1사분기 TV 출하량은 970만대로 전년 동기 대비 4% 감소하여 삼성전자의 VD 사업부 영업이익은 4% 수준에 머물렀다. LG전자의 HE 사업부 영업이익 대비 10%나 낮다.

이 대표는 ‘삼성전자는 매출이 줄어도 영업이익 확보를 우선시 할 것으로 예상됨에 따라, 65 inch 이상의 초대형 크기 제품 프로모션에 집중할 것’이라 언급했다.

현재 삼성전자는 프리미엄 TV시장에서의 점유율을 높이고자 QD-OLED를 TV panel로 이용할 계획이다. QD-OLED는 blue OLED를 광원으로 사용하고 그 빛이 QDCF(quantum dot color filter)를 통과하여 red와 green 색을 구현하는 기술이다.

이 대표는 QD-OLED의 성공 요소로는 65 inch 이상 8K OLED panel 생산 등이라 말한 반면, LG디스플레이의 10.5세대 OLED 조기 투자로 인한 프리미엄 TV시장 포화가 위협 요소로 작용될 것이라 언급했다.

유비리서치가 4월 발간한 ‘2018 OLED 발광재료 산업 보고서’에 따르면, QD-OLED는 top emission 방식이기 때문에 TFT 방향으로 빛이 방출되는 bottom emission 대비 개구율이 약 70% 증가되어 8K 해상도와 고휘도 구현이 기존 WRGB OLED보다 유리하다. 또한, 색재현율이 높은 QD 재료를 color filter로 사용하여 UHD 색 규격인 BT. 2020에 도달이 가능할 것으로 예상된다.

<기존 WRGB OLED(좌)와 QD-OLED(우) 구조, 출처: 유비리서치>

한편, 유비리서치는 OLED TV의 매출액은 연평균 약 30% 증가하여 2022년 약 57억 달러 규모가 될 것이라 전망하였다.
